alright first of all, i really love the look of the game, man. the visuals look very appealing! :D

now as for the gameplay, i was able to have quite a stable FPS for my potato setup, something between 20 to 30 FPS i think, lol. 

the movement does feel like everything's slippery, and the camera sensitivity was too sensitive for me although it's easy to get used it nonetheless. 

similar to the first feedback comment here, the fire's collision area could be a bit smaller or at least make it look like the particles hit the player before dying. i'll also add request that maybe you could try implementing where you stop moving on slopes, but if that'll be fixed when you adjust the movement's friction, you can disregard that request. :P

i've also sent you a video on twitter of a weird glitch or bug where the player just freaks out. restarting the game doesn't fix it either. :<

that's all i could say pretty much, i also wasn't able to play the game for too long since i get laggy and the movement's pretty difficult. looking forward to improvements of the game though! cheers :D
