Ah, hello fellow developer of a "shady company" game! Nice to meet you!
The controls were pleasant enough, and I especially respected the ability to use your mouse to skip through dialogue. The notebook entries were also pretty interesting.
However, unless I was paying attention to the dialogue at the start of each level, I had no idea what to do. So I'd get caught in some trap or find my way back to base and not know whether or not I did the right thing. I think some sort of interface in the corner of the screen would've done wonders for this issue.
Another gripe is that the game just...feels empty. There's barely any music and the only sound effects are the diver. Some sort of underwater ambiance or slow-moving background music would've made the game feel a bit fuller.
Overall, it's a novel concept and a clever extension of the theme, but I felt like it just felt a bit amateurish in presentation (especially with the spelling/grammatical errors). I'd love to see an enhanced version after the jam tho!
