This is a pretty complex shooter but I like it! You've good good music, cool graphics, very nice variation on sound effects, great UI for the cooldowns, an in game tutorial that you can revisit, and most importantly cookies. The rewinding mechanic is confusing at first, but I think I got the hang of it. I think it's really interesting that if one person is in the rewind, the next person that gets shot dies because it's a paradox. I was wondering why have the yellow blaster at all if you have to shoot someone twice to kill them anyway, and I realized that lets you save your rewind. The robots are REALLY good at leading their shots which makes this game really hard until I realized the importance of the yellow blaster. The graphics style really reminded me of old 90s shooters which fit the vibe really well.
Awesome job!
