The difficulty of the game is fairly steep, I got to about the 4th or 5th level and found that the levels were not easy at all compared to the introductory ones. Sometimes I would encounter issues where the counts of my items would change mid-level; I would have 2 jumps and 2 reverses at the start and somewhere I would gain a jump but lose a reverse. With a bit of polishing and bugfixing, I think this would be a very solid game. Nice work.
