Our Story
:wave: Hi, we are Bob Huijbregts (Development) & Maarten van Broekhoven (Game Design & Art).
Two devs and dads who have far to little time for game jams. We made this game in only 3 (late) evenings!
It's not perfect by a long shot, but still we are glad to have joined Ludum Dare 49!!
This is the first sketch of the game idea:
And this is how it turned out:
Audio
Sound Effects are all found on artlist.io and slightly modified to fit the game. The radio messages are recorded by Maarten. We opted-out of the audio rating because the radio messages are the only sounds we recorded ourselves.
:raised_hands: Thank you for playing, rating and commenting!

One nit-pick I'd have is, that I'm personally not a big fan of the shots having both random scatter AND limited ammo.
One quick note: You should classify the Link as HTML5 instead of "source code". I nearly skipped that one, because I didn't feel like building it myself :D
Thanx for playing.
Audio is also nice and satisfying.
I'd say the ammo mechanic incentivises gameplay were you want to avoid enemies more than attack them, so a dodge/dash would be nice.
Also the camera movement is disorienting, if that camera movement and camera shake can be reduced a bit it'll be friendlier to more players.
I finally had the time to come back and rate everything I played so far!
