I enjoyed it. Has some issues, though:
- Very hard to push boxes, much harder than pulling;
- Couldn't immediately figure out how to throw;
- Combining two words in the title like that really messes up pronunciation!!! I named a game like that, didn't go well.
- Bug: Tinker gets stuck in the wall after building a box;
- Bug: Characters can't turn left when standing still, that one "Else" should be an "If";
On the other hand, lovely puzzle design! All abilities are well-thought-out. The Fan mechanic is really fun: they can act both as help and hindrance, could even say I'm a big Fan of that.
