This is a fun and punishing platformer, it's surprisingly easy to control despite the backwards controls. I like that the spikes and fruits are reversed for what they do in the game too! I got stuck on I think level 4 because the double jump was really inconsistent for me, I could only single jump most of the time and occasionally the double jump would work, but I needed to double jump to clear some water I think and it never worked for me there. Great job on this tho I had fun playing it!
