Got to the second level and quit a little after getting the canister launcher. Restarting from the beginning of the level just makes it too tedious. It feels kinda weird that you have so much speed while the optimal strategy is to go slow as possible. Maybe slow down enemy projectiles so they can be dodged better.
Enemies can be kind of hard to differentiate at the distance and reaction speed of the gameplay. I'd give their masks different, bright colors.
Also I was repeatedly told that this game's levels suck, and I'm reporting you to the authorities for false meme advertising because they're pretty decent.
I read some of the other comments, but I'm gonna have to disagree with them on disliking the handgun, I think it has a really nice rhythm for plap-plap-plapping bad guys.
