Welcome to AstroPhysical!
A massive asteroid is hurtling towards Earth. The impact is, frankly, inevitable. But don't worry! Using the many tools in your arsenal, you can give the citizens of earth a few extra hours to live out their lives in peace :)
MAKE SURE TO DO THE TUTORIAL! On your first playthrough, press "New Game".
Changelog:
04/04/2022 - Fixed game breaking bug in "end game" screen - permitted by LD rules.
05/04/2022 - Fixed bug where you could (for some reason) spam the gravity tractors all over the screen, and yet still the gravity tractors were not working (this is what happens with 2 days of no sleep :P )
08/04/2022 - Fixed gravity tractors (again) and bug where tutorial would skip if you clicked anywhere but the dialogue boxes
Have fun! And remember to post your score in the comments :D

It is a great game for aspiring pianists jaja as you need to do multitasking with both hands :)
Thanks for this entry.
It's a bit of a shame that, when you smash the asteroids to smaller pieces, the smaller pieces _almost_ follow the same trajectory, so most actions actually don't delay the asteroid as much. I tried breaking stuff up into smaller pieces and then deploying the gravity thing, but that didn't seem to do much.
The nuke was cool! Though the first time I could deploy it I lost the game while in nuke mode, so it sort of got stuck until I pressed escape, then I lost my mouse cursor. I thought it was a weird, buggy ending screen at first because of that :-p
And thanks for informing me about the nuke bug! That was a scenario I had (for whatever reason) not considered and will be sure to fix soon :grin:
Also not sure I got how gravity tractors works, because seems mine doesn't do anything :)
Found little bug where you can fill ore when it already filled up
Noice you've added seems not fitting for me
Overall good entry, also this game reminds me of games like "Please, don't touch anything"
@rhoka I think in retrospect it's clear I overestimated the player (as most new developers usually do :sweat:) Perhaps in the next (mobile) iteration I will reduce the values across the board for the abilities. Thanks for the feedback!
-I think the noise on the screen is a bit set too high
-During the tutorial the time should be paused or you are tempted to jump to the game right away
But overall the best game I have tested so far!
Some systems might use a tutorial or a bit of improvement (looking at the solar generator :sweat_smile:). But for a compo -- a very solid job! It looks very nice; sfx, music and humor -- all's there. Great job!
Thanks for coming to my stream! Here's a recording in case you'd like to refer to it https://www.youtube.com/watch?v=WudvDztkwdg
Good job!
@wfmg Thanks for dropping by! Yes, that is indeed the look I was going for :D
@eboatwright Oh wow that sucks! It works on my friend's Linux computer although I'll update the Linux target nonetheless. Hope you can try it on a Windows VM if it still doesn't work!
To "Nuke", you need 15 ore. Mine uranium by clicking the circles in the bottom-left "green" box, and then "fill" it by clicking the red "FILL" button in the ore tank in the far-right.
Missiles auto-replenish their resources over time (Steel).
To use the Solar Beam, you need 10 MWs of energy. To get this energy, simply line up the moving green line with the white one and press space! Each successful lineup is +1 MW.
As for the Gravity Tractors, their cost changes after each use, and is labelled beneath the button.
I really hope you can give it another try and please let me know if this helped! :D
The linux build worked okay for me by the way!

Things I liked:
The graphics were superb, really loved the models that you used & also the filter over the screen.
The music wasn't annoyingly repetitive (given that each playthrough is relatively short.
The UI was really easy to use/understand (maybe it could be better with keyboard macros for each button the player can press? Unless that would make it too easy?)
The game fit the theme perfectly.
Things I didn't like:
The music had a gap between the end of the loop and the start of the next.
The text box wasn't satisfying to click, so the tutorial felt too long each time.
The timer starts even when going through the tutorial which for the first playthrough was stressing me out that I might die before I finished the tutorial lol.
@poontangular Thank you for the feedback! It was my first time experimenting with music so I understand if it has a ton of issues :sweat_smile: The tutorial was also quite rushed, I basically created it entirely during the submission time so it can be quite crude. Glad you were able to enjoy :D
The only thing that frustrated me at first was that nothing felt very impactful against the asteroid. Even when I split them into tons of tiny pieces with the solar beam, those pieces were just new hazards that could end my game. Then obviously I realized :bulb: oh yeah, inevitable. It's a great fit for the theme. If you had any plans to continue this into a full game (and I think you could, this is a really good base), my opinion would be to go for a game you can win. The weapons could drive asteroids back further, or could actually destroy small pieces so they aren't a threat anymore.
After realizing that breaking the asteroid into more pieces maybe wasn't in my best interest, I tried just using gravity tractors behind the asteroid to slow it down. The first one I placed behind it, I noticed actually nudge the asteroid forward. So the next few I placed just in front of the asteroid and it would sometimes get pushed back. I ended up using them as just physical obstacles and got my best score of 130 lol. No blame on you for that, that's me poking around and exploiting haha.
Btw congrats on the 130! Beats my personal best of 128 :D I believe another streamer once got a score of 150 by exploiting the tractors lol
Once I figured out how to make use of everything, I found myself preparing a lot of ore and energy. Nukes, then missiles? Solar beams, then gravity wells?
I found the game dynamics compelling, but I struggled with the visuals. The bloomy static made me feel like I needed to squint, and I got a bit of a headache.
When I launched the nuke, I liked the 1st person view (a little jarring the first time), but unfortunately if I missed...I didn't know how to get back to normal view, and I didn't seem to have a lot of degrees of freedom in terms of turning, so I couldn't seem to hit the meteor or anything.
Cool idea, and great implementation!
