I really like the idea! However, the controls did not do it justice.
1. the fact that you cant place tiles on the far right and far left side cause my guy to fall through way too many times. :(
2. the movement of the tiles was really choppy. I felt like I could never place them where I want to. They always slided way too right or left or way too up or down. It was annoying.
3. getting rid of tiles would be a welcomed feature, my little guy got stuck between two again too many times.
However as I said, I loved the idea! The art was reallynice, the little guy turning around was really well done. The sound design also suits it really well. Overall, great job! I know that balancing is really hard in gamejams, so dont take my feedback too harsh please. :D Congrats!
