The others weren't kidding, this is hard! It was oddly addicting slowly improving my progress. Kinda reminds me of the chase sequences in Ori, which is definitely a good comparison :D
Great stuff for your first game! The controls felt good, which is one of the most important things to get right for a platformer. My only real feedback is that sometimes it was a bit hard to tell which tiles had collision and which were just background decoration at times.
