Hello, just played up to level 3, i gave up when i realised i had to do one and 2 all over again. I like the aestethics and the feel of the game. and for what i have seen the level design is really good, the introduction of mushrooms and spikes step by step, i wouldn't change a thing on that. I don't know if that's what you are going for but the spikes are very unforgiving. I also think you should adapt your camera, when the player is moving, only one third of the screen is in front of the player, the rest is unused, i believe GMTK made a good video on the subject if your interested, (for the vertical axis i have nothing to say it's perfect). Last thing it was very fustrating for me to retry from the very beggining and redo all the easier part again and again at every mistake. Good luck for this game keep going.
