Good ideas. Like the idea of moving something dynamic, like liquid or a fluid. Kept getting stuck on the tutorial: could not move my block up to leap over the chasm or get down to the lowest level.
Maybe try using a sphere instead of a square. Use an object smaller than the obstacles that when possible can move through spaces so the player does not get their moving object stuck.
I agree with the other reviewers: physics need work and the controls are taxing for the player's fingers and hands and wrist.
So much potential. Execution leaves much to be desired. Revisit reworking this game, you have something here worthwhile.
5/10.
