a very nice and kind of hard platformer for me anyways but having a difficulty system would make your game really enjoyable like just having more time if it was easy or normal and hard I guess would be this lol.
another thing I might add is maybe make the hitbox of the player for the spikes a little smaller but I am probably just a noob lol regardless I loved the art and the movement was smooth the particles were also very nice. I loved it good jobb
