Bigger rooms are moar fun, change my wandmind!
So, I liked the simplicity - no spells, no nothing, just wand goes brrr! Definitely had some fun!
About dungeon designer - I only understood the deal with it after following a link to OG game - you were making "build to scale" game it seems. Well, right know it's feels somewhat forced, and, I believe, it would benefit from a bunch of simple options, like changing the number of rooms (YES GIMME ONE THE BIGGEST ROOM!), "generate random", only squares and so on.
Also, maybe it would be nice to receive rewards during combat (with no pause on hard mode, lol)
