Ok. First things first, an advice for a unity developer not using Web Builds. Way more people play web builds, than downloads. So click those build options, and make web builds!
Now for the game. I liked it! Graphics and music was alright. The feedback on getting hit, and hitting enemies was clear. The controls were really good (points for having keyboard and gamepad version) and responsive.
I especially liked the number of different powerups. Each affected the gameplay in a different way, so that's cool!
I'd like to see it more than a wave beat-em-up, with proper levels, different backgrounds, and, dare I say it, a boss at some point!
Also some result screen would be nice. Like "you defeated this many baddies, survived that many waves, collected this many glasses".
