I really liked this game the movement feels cool, and the music is pleasant!
A few negative notes regarding game/level design: the tutorial on the side is pretty neat, but since you're moving fast, you don't really have time to read it. The issue is that the jump explaining the shoot mechanic (which is crucial for what comes next) can actually be cleared without creating a platform. Because of that, I ended up getting stuck later on without understanding how to progress.
From a gameplay perspective, the platform-creation mechanic is super cool, but it's a shame the simple shot isn't used for anything else (like opening doors or killing enemies, for example).
As mentioned in a previous comment, moving the Q and E controls to the mouse buttons might have been a bit clearer.
The wall run can also feel a bit frustrating at times since you can't re-attach to the same wall.
Sometimes the "Q" key doesn't register, which is a little frustrating.
From a speedrunning perspective, I would have loved a key to restart at any time and an option to skip the intro dialogue!
I know I gave quite a bit of feedback, but I honestly had a great time playing!
Thanks, and great job to the team!
