Thank you for the kind worlds! I agree on the harshness of the game overs... was just reflecting on some ways to make the game more friendly - just had a cute idea that the robots would deconstruct any blocks that were too close to the spawn point... With some penalty.
I think I was trying to stick to the original Squarez game concept too closely - it was very tough and even unfair at times (there are blocks that move the walls and make the board smaller!) and ones that create an iron cross of metal squares.
Also agree on the lack of explanation on the mechanics - I had a stretch goal to add tutorial sections but alas time caught up :) Thanks again, the feedback means a lot as I poured my heart into this one.
