Very polished puzzle game for such a short space of time! The levels scale up the difficulty nicely, once the boxes got involved there were some interesting and clever interactions. I liked the UX touches, such as being able to quickly countdown the counter once you'd hit a winning position. Great fun, great job!
Some constructive feedback:
- A level counter would be good, I didn't make it to the end but if I knew there were only a few more levels I may have continued!
