Hello! As an idea for improvement, a small introductory guide would be helpful, as well as some way to shorten the route between the stalls — running back and forth along the corridor feels quite tiring. Alternatively, you could add hints about what’s happening in different areas without requiring the player to run there every time.
It’s clear that you took on a very large amount of work and simply didn’t have enough time to test everything thoroughly during development. In any case, well done!
