Though Dragonsweeper is more refined, I'm actually having more fun playing this game.
There is one major quality of life improvement I'd like though, as of right now, it seems to be impossible to mark tiles on mobile. This doesn't break the game, but it is annoying.
...Also, is it even possible to get the Advanced/Master Annihilator achievements? I haven't been able to find a way to kill the Balrog, so there's no way to totally clear floors 3 and 4, unless I'm missing something.
It would also be nice if there were a few more rewards for achievements. Maybe say, having certain achievements give some money and unlock a shop prior you could use prior to the first floor?
