Yeah, we didn't want floaty gravity since it didn't really fit with the pacing we were trying to create. To compensate though, we made the jump really high and even added a double jump to make the jumps as fair as possible.
As for the difficulty, we have every intention of adding different difficulty settings so that the player can enjoy the game regardless of their skill level. We just have to wait until the rating process is finished before we can update the game, which is like 9 days from now I think
