What a nice platformer! the control is nice, but as a keyboard player, I somehow always defaulted to pressing up for jumping - A feedback I can give about control is that if I kept holding the right arrow as the game restarts, it doesn't register my the input - I think people do tend to do this upon restarting.
I only managed to get to the level where I need to keep jumping on the bats, but I don't think I'm understanding the physics of the jump as sometimes it feels like it should bounce more and sometimes it doesn't - quite possibly my issue but some kind of explanation would've helped clarify the game mechanic. It was quite the challenge but it was also fun!
It's also a shame that you're lacking and audio which will make this submission feel a lot better, but great job nonetheless!
