That story was quite a wild ride haha XD
The premise was super interesting but i like how it got more of a humorous spin thanks to some of the wacky stuff you come across the lab and i did not expect the text to speech voice but it was quite nice to have everything be explained via quick dialogue bits rather than walls of text, so that's also a plus game design wise ^^
I had a few issues here and there, the controls mapping is a bit odd with having jump on the up direction rather than a dedicated button, and the difficulty has some wild inconsistant spikes at some points, the begining especially since you spend quite a long time defenseless against enemies, it gets better once you're not anymore, with one oddity though, even crouched you can't kill some enemies.
Same sorta goes about the gas mask powerup, the leaks are dealing devastating damage and sometimes i got killed from the knockback just because i tried to move on but there were still a few pixels of gas near the floor so i got thrown back into the other leaked that comboed me and killed me right away, now that being said death had me laugh cause of that wilhelm scream you put in there :p
Other than these, it was really fun, i managed to play the whole way through, and the powerups were really interesting.
Well done :)
