Art: It's fine. The 8-bit aesthetic suits the game design choices. The perspective on the cover art is wonky, though. The top part of the tower, platform, and front part of the catwalk all seem to be viewed at different angles to me.
Writing: I'm glad someone did a jailbreak! It seems like something we should see a lot of in Mothership, but don't. There are a lot of grammatical errors however, and the use of "you" seems directed at the players, whereas it's going to be the Warden who reads this. The story doesn't totally make sense... like, why did the jail surface and let everyone out of their cells but not disable the bombs?
Game Design: Given that you seem to be trying to write a TTRPG that feels like a CRPG, you did a decently good job of that. There's lot of running around to find keycards while dodging three different types of enemy which are each threatening in different ways. There's a logic puzzle to make sure you rescue the right person, and "power ups" to help you if you do the side quests. There are things you could do to make this appealing to a wider audience, but as long as you're aiming specifically for CRPG players it's fine.
Theme: I guess the idea is that Alcatraz is a legendary prison and could be mythical in the distant future? I'm not really seeing it.
Layout: Pretty functional. The 8-bit style impedes readability a bit.
Utility: I'm confident that I could run the adventure as intended without much prep.
Favorability: Unfortunately, this is exactly not my jam. I think CRPGs do a bad job of capturing what makes TTRPGs interesting to me, so I won't play anything that kind of back-migrates the shortcomings of CRPGs into a TTRPG format. (But don't worry, that didn't affect my other ratings, only this one.)
