Right off the bat, awesome CRT filter and logo effect. It looks awesome!
I really like the gameplay. Like, a LOT. Kicking yourself off with bullets and going everywhere while also being able to slow time. It's just so well put together and flows super nicely!
The sound effects are super satisfying, and I really appreciate the fact you didn't put an ammo limit. Just lets the player have fun shooting away!
A random suggestion I have of something for the future is a timer for speedrunners!
Everything here is just really good, and I would love to see this expanded into a full game. This game's sick!
