✦ AI summary
Players criticize the game for significant technical instability, confusing interface design, and lack of clear guidance, making it feel unfinished at release. However, some appreciate its potential and note the developer is responsive to bug reports, though these positives don't outweigh the frustration most experience with core functionality and usability issues.
The game is not stable and should not have been released.8 found this helpful
As someone who plays many diamonds in the rough I tend to have a good amount of patience for weirdness/unpolishedness. This game is beyond that. Plenty of bugs, I can't figure how to stop the screen from flashing when clicking, no upgrade menus but floatable windows which get in the way. Progressing and unlocking achievements while I still haven't even started figuring out how things work.8 found this helpful
