Pretty solid little metroidvania. The ceiling cling ability is really clever and I really like a lot of the ways it was used. Other abilities are pretty standard so not as much to say about them but they were competently implemented.
As far as the basic player controller goes I feel like they were just a little bit slower than I would've liked, and that they could use some inertia on their movement to make it feel a bit smoother. Both of those are minor nitpicks though and the game felt perfectly fine to control.
Combat was pretty lame honestly. The player's attack is really annoyingly short range and made it hard to avoid damage, and every enemy including the bosses having the same AI made it feel a bit boring, especially for those bossfights. Though I feel like that's kind of an obvious flaw that you're probably aware of and just didn't have time to do any more with.
The art is nicely done, though some background elements would've been nice :P. I also feel like the tileset kind of clashed with the theming of the other objects - the blueish stone looking bricks gave me more medieval dungeon than modern lab vibes, which made it look a bit awkward next to all the very modern looking doors and scientists.
Music was good quality but honestly didn't feel like it tended to fit the scene very well? It often felt uplifting while the visuals and writing were trying to create a desolate, derelict kind of vibe. Feel like something a bit darker would've fit better, especially in the room where you first encounter the possessed scientists.
Overall, decent game here, had fun playing it. Pretty solid entry.
