LevelUp!

not all graphics show up correctly on my Mac (looks like all font related stuff isn't rendered correctly) couldn't really find the 10-seconds twist on it, but it plays just fine! :)

Good game, it's very difficult! oO
I always die when I'm level 3 or 4...

It worked well for me in Chrome on Windows 7. Fun game!

dude your game is amazing, i am a sucker for game mechanics that are challenging and fun.

Awesome!

Nice! But pretty hard to survive a bit longer. Also, given that all enemy trajectories are linear towards you, I wonder what bullet speed is good for?

@timtipgames yeah, I think it's pretty useless right now, my first idea of this game was slightly different. :) The key to win at higher levels is to use the Up/Down arrows to rotate the player by 180 degrees. I know it's still too hard though. :D

I like the simple graphic style.

heh, nice game! simple yet satisfying.

Fun game, simple concept, amazing result. 9/10 would play again.

Got a score of 96! Level like 20 or something.

Very good and basic concept that was executed well.

The sounds were terrible though. Sounds like they were made with BFGR (nothing wrong with that), so next time spend a few more minutes finding sounds that AREN'T incredibly obnoxious.

Good fun stuff besides!

Nice, pretty fair and challenging. Not bad for a day's work.

Decent game. The upgrades seems a bit weak.

Neat little tower defense game

Really fun! Pretty addictive! I liked how limited you feel at the beginning of it. It would have been nice to see a more obvious display of how long till you level up. Also, bullet speed is a useless upgrade, because it doesn't help you in any way. You could have made larger bullets, or maybe multi bullets instead.

This game is very fun! Super job for 48 hours!

Stunning little entry - I loved the progression, simplicity, and unique control mechanic - congrats on pulling this off!
