This was the most fun I had so far rating games from this jam. I actually really like the choice of not knowing what the "player" is going to be doing and having to discover that first, and then plan the level around it. And taking advantage of that vertical space later on.
And THANK YOU for letting me use keyboard shortcuts to place the blocks. I did find myself wanting to click and drag to place multiple blocks but it's totally understandable to have to click each one for a game jam. Another really nice polish thing I noticed is that when you right click to delete a block, the next block you go to place is automatically set to that. Great choice.
There were at least a couple levels that had me laughing once I pulled them off.
I didn't encounter any bugs or glitches. Great job!
