In the Android version I have just released, I will add levels and puzzles. This jam was about destruction and basically I didn't have much time for it (My eldest daughter had two birthday's last weekend, a house full of people, between moments I coded some, after I came up with the idea on Friday (most I wrote on Sunday :D) Thanks for your suggestions, I really appreciate them. I did increase the colliders on the boxes already, but I guess they could be a bit bigger still...I just want the tension to be there, so people shouldn't be expecting to hit 100% on the boxes :D
