Thanks! I thought of making a rollback button or backstep but didn't think it was needed. Now you have to be more careful before making inputs. Maybe I'll add it as a feature in the next version though.
For twists in puching mechanics I'm thinking of making solid Rocks/Trees that cant be pushed as well as maybe have other objects that behaves differently, heavier rocks, logs/objects/boxes that only move one tile at a time. Along with that there is alot to tweek when it comes to level design and difficulty curve etc. Maybe just adding different grass and water tiles that animates the scene etc.
Thanks for testing out the mobile port! Im fairly satisfied with it, but I myselfe keep missing the input pads sometimes so maybe some tweeking there is needed as well.
