Overall the game is pretty fun, and the concept is really cool. I liked the music a lot (specially the one in the final level), makes it way more intense. The dash feels really good and the level design is really interesting. Sound design is nice too.
Now, the physics kind of make the game quite more tough and painful than it actually is.
- The ceiling corner adjusting feels way too excessive, and usually makes most jumps a nightmare to control, specially in tiny gaps. (For example, Stage 11 at the start of second checkpoint, you must take like a lot of time to properly do either a good dash into the top platform, or jump and not get either corner adjusted into the wall of spikes, or pushed back down.)
- Floor corner adjust also feels weird sometimes, making some jumps really hard to control or make you slide when trying to land. Paired with the really low air control makes a lot of sections way harder and frustrating (like Stage 20 top-most section)
- Sometimes you get a lot of missing inputs, specially jumps (This might also be related to the floor corner thing, since you usually will start sliding earlier and you cant jump off from this state). Some other times you're just running, and try to jump and won't get registered. Other times you're holding jump and a direction and the dash won't get registered.
Still, a quite fun game, I'd love to see more gameplay fix updates.
