Excellent game! I agree with another commenter that spamming rolls is a bit of a "cheese" strategy. In the section where you had to fight through a bunch of enemies to get back to the surface, I was able to just ignore every enemy by rolling through them.
Another thing I would've liked to see is being able to roll forward while stationary. Often, I would be shooting something, it would come close, then I would press down to try and roll through it. But then I forget I have to be moving to roll and stand there foolishly while something rips apart my entrails. It just felt awkward having to press two things to dodge.
Other than that, the art style is great and you do a good job of not over-explaining the situation, leaving a decent amount to player imagination.
Fans of SCP will love this!
