Very good concept. It would be fun to me if the game started right away instead of a hotkey press and you'd quickly need to build the blocks for the player.

I got a few possible bugs. In the 2nd level, player teleported instantly half the screen towards the goal from the money. Player took a very long time to turn around towards the goal even with all the blocks. 4th level, the player fell inside a box, got stuck there and the game froze, couldn't restart. 

Good game!

The idea behind this game is one of the best I've seen so far, and it's executed properly!

Well done

This is a super cool idea!  I had a lot of fun finding the different ways to rearrange the stage, and I liked that the game allowed you to move blocks around both before and after you activate the player.  I was pleasantly surprised not to run into any bugs, as games where you can move the level like this tend to have a lot of issues, so well done on making sure everything worked properly!  The main criticism I would make is that I wish the player movement were a bit more predictable.  I think adding a layer of randomness to how the character moves is great and forces the player to react accordingly, but there were a few times when the character just kept walking away from the flag towards nothing and I just had to wait for it to turn around.  Overall though, this is a great idea, and you executed it really well.  It's a shame that it hasn't gotten more attention up to now.  Well done, and congrats on finishing in the jam window!
