Based on what I played, I'm going to assume that this game is still unfinished. Going off of that, I'll break down what I thought worked well and what I didn't.
First off, I like the idea of the dynamic camera. It's a good idea, and I like how it snaps in on the classrooms, and back out for larger halls, shafts, etc. The attack power was limited, but it was pretty satisfying to nail enemies with it once I got the hang of it. I didn't fully understand the dash at first, but once I figured it out that works decently too. I like the character animations, and little touches like the dust being kicked up as she runs.
For areas that could use some polish and improvement, the overall control is maybe a little touchy, and the camera, though a cool idea, is a little fast and erratic at times. One odd thing is I seem to start on the roof when the game starts, but if I die there, I teleport to a classroom that seems like a proper starting point. Speaking of dieing, the "S" key deals damage to yourself? Being the key inbetween the left and right keys, that can be a problem.
I made to the point with the floating platforms and laser turrets, but couldn't get any further... the platforming, camera, and barrage of laser attacks were to hard to get by.
Overall, it's rough but has potential! I hope you keep working on it, as I like a lot of what's here. Nice job!
