It definitely has potential, but need some rebalance. Charging routine is TOO WAY LONG. It's not very funny to play the game where 80% of time you need to charge your gun and dodge bullets. Shooting is not feeling responsive. After laser beam is casted it's reamain its initial position, but the enemies are way too speedy, so it's too hard to shot em... 

Simple graphics is cool way to make the enemies distinguishable and to stand out

Overall, I see it could be cool game with fun gameplay, but for now it needs some balance and tweaking! Thank you for your submission! :3

I really love the crisp geometric abstract art you have going for the characters! Also, the sound effects were pretty silly. Always a fan of the most reliable instrument (our mouths). Gameplay was nifty too! 

I think if I could provide quick feedback, I'd probably suggest focusing on one art style when it comes to how you express your game both via visuals and audio. Like if you go with these cool abstract characters, it may clash with your mouth effects. Same for your background, the garden grass kind of seems like a more warm cozy aesthetic versus the silliness you have in your sounds, and sci-fi-y-ness you got going on with your characters. 

Regardless, had fun! If you keep working on this, keep it up!
