Hello! Seems like we have a slimesweeper in our hands. First of all, congratulations for being able to program it in RPG Maker. The game doesn't present itself well, but at least it's the gameplay that counts, right?
Though I personally found myself lost multiple times during the puzzle, I felt like that there were no right solution a bunch of times, and I had to try it at random. I suppose it's not completely unfair, since you can know how many slimes are there in total, but thinking ahead that much requires some experience - and an extra tool to mark "hypotetical mines" that the game does not provide. Also having a field that lies makes for a very unfair addition in my opinion, since you cannot trust any number so making the minigame impossible to solidly reason to.
If you're curious I streamed the game. Here's the vod: https://www.twitch.tv/videos/2482229907
