Fun little puzzle game.
Definitely a little rough around the edges, but there were some interesting puzzles that make good use of the simplistic mechanics.
I really like how the double jump leaves a platform that you can use as an environment object (even if its prone to breaking things lol), and that in itself can already do a lot of heavy lifting in puzzle design!
Also really like the art and general visuals.
With some polish on the soft lock issues, and a little bit of preventative measures (I got to the GG and then fell into the void cause there were no colliders on the side, so I think that was the end?), then you could expand this into a fun Shiori-based puzzler! Good work!
