Quite a few grammatical issues in the dialogue, such as not capitalizing I's and first letter of each sentence, incorrect word choice (e.g. "corrupted" politician instead of "corrupt"), etc. I suggest running your dialogue through a spellchecker. I feel like there is too much dialogue for some parts: for example, having the player character narrate that they're learning to jump and crouch in the tutorial is entirely redundant.
The loading screen was stuck at 50% for a while and was overall lengthy, and I had a huge performance drop after it finished. Spent uncomfortably long trying to find a way outside, maybe I'm stupid but I feel like it should be a little more obvious.
Pressing F to speak with the nurse repeatedly restarts the dialogue, even if I'm in the middle of it. I just beat the guard up instead of finding the vents.
I think the spritework for the world characters is fine, but the VN drawings a bit poor. I would either lower the resolution to make them match the world sprites more, or keep the resolution and increase the level of detail.
Can't say that I enjoyed this game unfortunately, maybe it's just not for me.
