Awesome game :D! Loved it :)!
Found at least two bugs, probably more.
1. After trying the level with sticking to boxes (15 I think) somehow, heroes would get into their sticked state (after first action, I think), even after pressing "NEW GAME" - in level 1!
2. Get to the stairs with one creature and have at least another one. Then move with the creature you went into the stairs with (yep, that's possible). Now you're stuck.
It would also be great if you could restart with a key, 'R' for example.
This might be an amazing mobile game :D!
Good luck with this game and with future projects :)!
