This was fun! First time: 25:43 and 36 deaths. I think I sequence broke a few levels towards the end by abusing teleporter mechanics which could make for some fun speedrunning. The level where you accelerate towards a teleporter at the very beginning you can just shoot into and pass right over the teleporter xD
One thing that was a bit annoying were the one-block ledges which weren't part of the puzzles. For this game maybe sloped edges could have helped with that. Some levels did feel a bit long but mostly I really enjoyed them, especially the !-blocks were a fun mechanic and I think you had some nice puzzles with those and the teleporter.
I liked the giraffe sprite but didn't care much for the story in this type of game. Music was top notch!
