To whoever came up with the idea of "half-moves"; there is a special place in Hell for you. The game is a decent enough puzzler, some of the puzzles take a little extra time and some trial-and-error before the solutuon presents itself. BUT near the end is a level with tons of ladders, 1 heart and an armadillo enemy chasing you. When moving forward It takes 2 steps to move, 1 is a half-step. In 90 tries of that level I died every single time because of a half-step.
