From the developer

Built by a solo developer. The features I set out to make are all in — this launches as a complete game.

I'll keep updating it after release, at a steady solo pace, based on your feedback.

AI Generated Content Disclosure

The developers describe how their game uses AI Generated Content like this:

This game uses generative AI as a development aid. Specifically, AI was used to
help create some illustrations (backgrounds and store key art) and to assist
with the localization (translation) of in-game text. All AI output was reviewed
and adjusted by hand, and we have confirmed it contains no material that
infringes third-party rights or any illegal/inappropriate content. No AI content
is generated live during gameplay.
