Very fun little space shooter! The music and sound effects were great. I think the time freeze mechanic is quite interesting and nice, and I especially liked how it was just a gauge that refilled on its own. The enemy and projectile types were varied and fun. A few things I felt as I played:
1. You can shoot enemies that aren't even visible on the screen yet -- I felt I at least wanted to see them, even if for a split second!
2. There was no reason for me to not continue holding down space the entire time to keep shooting, as far as I could tell.
3. I didn't see any way to recover health, but I think it would feel a lot better if there were some kind of recovery item you could pick up if you were fast enough.
4. Time freeze on shift and special ability on control felt physically a bit difficult or awkward for my hand. I think it could use some other optional controls.
5. The tab crashed when I shot normal Ame's beam at Fubuzilla! Somethin' went wrong there.
I really enjoyed this though, great work!
