Talk about originality! A game about stacked dwarves xD. I had way more fun than I expected for a jam submission, it's an amazing result for just 48 hours of work, congrats man!
The only problem was the level everybody got stuck on (lvl 6), it takes away some of the fun, since it becomes frustrating. Difficulty growth must be a smooth curve, and I know this is something hard to achieve. Nearly all games I did, people complain about difficulty, I'm terible at making balanced difficulty.
EDIT: I managed to pass it! I had to jump on the platform with 3 dwarves, and with that momentum, I grabbed the 4th dwarf, then jumped with that "dwarf bridge" to salvation! And as I imagined, the level after that was much easier to pass (lvl 7), it didn't require much thinking, but more skill, which means the difficulty curve is a little unbalanced.
