Idea is good. Played a lot, hoping for a better start. I think furthest I managed to get was floor 6 or 7... Its quite brutal, since most of the runs I launch would end in floor 1 due to unlucky streak of the mob/loot spawn. Had run with 8 teleporter stones (didn't help me much!), had run where I got everything for physical heal and stuff, but got blocked by that mental mobs that I had no protection or cure from.
Would be MUCH better if you would do less floors for victory for a jam, since balancing that wouldn't be possible in that time frame. At least it would be more likely to get that victory screen... 13 floors of randomness is a lot of luck to get through!
What strange is that quite often if i would find hat on the level - it will be full of hats. In general felt like one item would be spammed on the same floor... or it just my luck...
