This was really fun.
I'll admit, I almost gave up at level 2 when the melee robots came in, because of the bug they seemed impossible to kill without losing a ton of HP. But I realized if you get real close they don't hurt you at all, so I continued playing. I'm really glad I did because I had a bunch of fun and ended up beating it.
I really like the artwork all around. I'm a sucker for glowy Tron lines. And I really appreciated that I could change my character's hair and shirt colors. The sword swing effects were really cool too. I didn't get all of the upgrades but the shotgun was fun to use.
If there's any feedback I could give, I would say the sword felt a little weak. It seemed like it was always the better option just to wait for my gun to cool down, especially after upgrading. I would say maybe add some helpful effect to the sword, like maybe the ability to reflect bullets or something, to keep it relevant even after upgrading your gun.
Honestly though, really good work!
