This was neat, if a little frustrating in the room just before getting the double jump. It could be a skill issue, but since you die in just one hit and the respawn is immediate, I'd sometimes end up back in the previous room since I had pressed back in an attempt to dodge an attack, only to die, respawn instantly, and get thrown back into the previous room all before my brain could register to let go. The projectiles also didn't reset on death, so sometimes I'd just get clipped as I respawned with little time to react. Outside of that, though, this was a fun little experience that I like the sorta 1-bit look of, though I will agree some music or sounds would be nice here just to fill it out a bit more. All and all, good work on making this!
