The Aesthetic and soundtrack really fit into the gameplay, the weapons feel good to use and kill the "monsters" with, even thou some of them feel a bit weak - but I think that is by design.
I felt like the game might need some indicator on the UI when you are holding a weapon, as there were couple times when I was running for a clutch lasergun and didn't pick it up - as I already had picked up a pistol by accident. But that is a minor thing, and it might be just me :D
Btw, I have to say the dash felt really intuitive and I actually used it before knowing that it was in the game (classic didn't read anything before jumping into the game) and comboing the dash with the sword felt great.
All in all, Good job!
