so this game definitely has a lot of thought put into it. It's an interesting story, and there are lots of inventive things you do with the way the environment changes (the gas effecting the rest of the environment, especially how it interacted with the other chemicals). However it needs a lot of polish imo.
The controls are kind of awkward and I felt like i never really had enough space to work with to make the movement feel good. I sense you were going for a more semi-realistic feel. The slow movement speed, jump movement, and the stagger on walking down steps did not feel great overall. I also was unable to finish due to a bug. After falling into the area where the floor gets melted, I got hit by an enemy, which somehow flung me to a completely different room, where I died quickly due to the confusion. Upon restarting, I was in a room which, due to the unceasing gas falling from the sky, meant I could no longer progress in the game. One last thing, is there some sort of bug with the music, the music track seems to have some very loud static going on through the whole track.
Some additional positives though. I love the voice in the game. Especially when Dr Kimmy mentions the big boi. I like the metroidvania style progress of opening up sections of the lab. And overall with some movement changes and polish this could be very good.
