so ive been playing it, and uhh its not fun i guess ? idk probably its because the framerate drop lol. however i didn't finish the game so idk if i could rate the game but i could give some criticism
first, implement a checkpoint >:(
its not fun playing the game over and over, if you actually implement a checkpoint, it might too far that i didn't reach it lol
second, the level design,
its probably also issue from my computer, i cant see the full game window so this might not true, but i think the camera is too close. i see that you are trying to tell the player location of the next platform by that collectible item. but its just better to show player the platform
