honestly, nice cat, but the design is quite anti-intuitive
- reverting in a "planning" stage should be cost-free. i suggest removing the doodle drawing stage entirely, and let the cat move on instruction --- this would make the undo payment more acceptable;
- the goal is to reach the treasure chest but u have to detour and visit every single tile, and then finish the last step at the treasure chest. forcing to grind without a good reason is bad. try telling the story better, common examples are
--- ending the journey on a stair of the next floor,
--- render cracks on the tiles to indicate fragileness for no stepping back, it may turn into water/lava after visiting,
--- let the player collect coins for optional detours, and keys/buttons for compulsory detours
