I had fun playing this game, I like the difficulty. Though as the person below me has already said, the part before the first checkpoint has the enemies walk in very tight spaces, I think they should have been given a bit more space to let the player have an easier time to squeeze in, especially since this is the start of. Aside from that I actually like how the some sections of the levels were designed. I like how there are optional challenges you have to go through if you want to get all the coins. I like how the droppable yellow enemies are introduced, I think the checkpoints are well placed, I pretty much enjoyed how every section of the level was designed. Another thing to suggest is to have the chasing section start by how far you are from the boss rather than how close you are from hitting the ground, because I found it nearly impossible to get to the end without starting off with a jump off of the boss's head. Overall I think this is actually a fun and challenging platformer. I actually gave this game a couple of runs and got an all coin + almost sub 2-minute completion on my 3rd run. good stuff!
