Fun game to play!
It really reminded me of Kairosoft games I used to play some years ago. Definitely could be made into a full game. I had a bit of an issue though, I don't know if it should work like that, but it felt like the heroes were taking forever to move out of the first room of the dungeon. They were constantly only walking there and not to the other rooms. Also something I think more people mentioned already, the game could be a little bit faster. Other than that, if you would expand it with some UI, that shows heroes and their stats and just provides more things to look at, it would be a great title. Congrats on making an entry, and good job!
