I was going through the games cause I had a free night and wanted to rate some of them, and I was like going throught them for 10/20 minutes each... I was enchanted by yours... I think I played it for almost 40 minutes... beautiful game.. really well made...
If I must say something that you could upgrade.. i think that when you saw that your solution was wrong, when you select the restart button, you go back to how you placed all the blocks and not to the beginning of the level, cause that thing took me at least 10 minutes in some of the levels haha
Anyway, this is one of the best one I've played so far in this Jam!
