There were some difficult sections (the one with the short rectangles of water that you have to dash and land on), but I managed the beat the game in 5:30 and 23 deaths :)
I'm glad the download is fixed, because this is an excellent platformer! Also I did not encounter any bugs, and the only "issue" I had is that it is hardwired in my brain that the up arrow will make the character jump, so I sometimes fell into the abyss because insted of pressing "C" I just walked off the edge and pressed "UP" lol.
Congratulations for making such a good game :) It's a lot of fun!
