We're glad the game kept you hooked for so long!
- We were considering implementing the idea that chests and mining were "real time" where the player loses invincibility in real time while performing them. So they would have to complete them faster to save on their invincibility.
- Definitely will play with the movement speed stats in future update
- Shops were actually one of the room types we wanted to add but didn't get around to! Along with random event rooms.
- Attacking enemies are an interesting concept. We are still contemplating how "chill" we want this incremental game to be. But it is something we want to test for sure.
Thanks for the great feedback and positive comments!
