As a fan of diagnostic procedure games such as Hardspace Shipbreaker, Uncle Chop's Rocket Shop, Papers Please, and so on, I like what this game was going for!
Unfortunately I didn't get to play it with other people since the servers are unpopulated, so I'm not seeing it in its ideal form, as I'm missing out on co-workers screwing each other over and other competitive aspects. Nonetheless, it was possible to play it solo, so I gave it a go.
As said, I like the general gameplay for the most part. Picking up jobs, diagnosing problems, finding the parts and then installing them: it's all my jam! However, while I do like it in concept, I have to admit that the execution didn't quite work for me, and I quickly found myself growing tired of it and quitting.
*I wish the tutorial was presented a bit better: ideally I'd love more pictures and diagrams instead of just text, but even if it was just text, I'd prefer that the sentences are spaced out, bolded, italicized, and colored differently to organize them in such a way to make more palatable. Something as simple as bolding the key verbs or objectives would go a long way to making the information more easy to retain and figure out at a glance: right now the critical instructions get lost in all the flavor text.
*I didn't like the match-3 repair minigame you had, and while one could argue that's a matter of taste, I think it had a lot of issues in its implementation. It's the exact same thing for different parts so there's no sense of progression or difference, it just feels tedious to have to rely on cards instead of being able to move freely, and why are cards even used when you can just keep drawing if you run out (shouldn't it be a challenging puzzle to complete with one hand)? I also just didn't understand the rules: I felt like I should be making matches with the associated part icons, with other matches giving no progress, but then some other matches did give progress, but I didn't know which?
*Finally, the game just felt very repetitive at its core with no real sense of meaningful progression, and with a short music loop that gets really annoying really quick.
For a game jam game, I do think this was heading in the right direction and doing some interesting stuff: I'm sure with more time this could've been fantastic and right up my alley!
