Quite a chaotic game. I had fun swimming around and mowing down enemies! Especially a fan of the electricity field, its so satisfying to activate it and watch all of the enemies get melted away. :D I got to level 15 / wave 11 I think!
Would have been nice to have some sort of visual cooldown on your electricity ability so you know when you have it again. Also some more enemy variety at later levels would've been cool!
Overall great job though, especially for your first game! :D
