The central mechanic of the dungeon being randomly connected frankly isn't fun. It could be made interesting, but I ended up just wandering aimlessly trying to find something that would advance the story before re-reading the description and realizing it might not actually have an ending at all. I'm not willing to keep poking at it to find out- there really needs to be something to give a sense of progress and keep you pushing forward.
There's a lot of typical "first RPG Maker game" issues- huge maps with little interactivity, a lack of music. It does at least avoid padding the game out with random encounters, and some of the dialogue is pretty funny. I can't say whether "overreliance on battles that aren't that fun" is an issue or not because I avoided combat entirely.
I do feel like the wrong parts were finished- it would have been far better to have a smaller dungeon with fewer maps and no overworld, but more stuff in each section of the dungeon and an ending. Alas, hindsight is 20/20.
