Loved it! Found it pretty difficult actually. The man character was extremely fragile! I felt like my inputs had to be very precise, which I enjoyed. I really liked the design of the character and the foreground bricks looked super nice. Some of the sound effects were really satisfying as well.
Most of all, I was really impressed with the level design. All of the levels had to work correctly forwards and backwards. The way the keys and doors were places forces you to go back through sections. When going the opposite way I had to rethink the area.
Great job!
