Note that this feedback is based on the build(s) available at the end of the jam.
As someone with fondness for and personal investment in text adventures, I was delighted to see this entry. ENDUSER is well written, and its balance of humour, self loathing and a familiar-but-odd view of its world makes for a delightfully surreal experience.
The "gimmick" of using various body parts as a verbs is fun, and a great exploration of the jam theme, but does get a little cumbersome over time. I'd love to see the game accept plural/singular variants for body parts (eg: "use brain" or "use hands") and have accelerators like tab completion and command history, but these are areas for potential polish rather than fundamental issues.
The game doesn't provide much in the way of directional cues, which on one hand makes it difficult to intentionally make progress, but on the other hand supports an air of aimlessness and awkwardness that I think supports the game's atmosphere.
The use of minor sound effects and music/ambient audio are great, and imbue ENDUSER's environments with a sense of oppressive indifference.
After exploring the apartment, venturing into the outside world, and diving into a dumpster, I eventually stopped after experiencing a crash. I'm looking forward to playing more, though, and hold ENDUSER as one of my favourite submissions this year.
I'd also like to do a short interview with you for an article I'm writing on the 2018 Linux Game Jam. Shoot me an email via cheese@cheesetalks.net and I'll send you through some questions!
