The core mechanic of placing down tiles is really dynamic and expressive.  I like the choice to make the rooms basically your health as well, it tightens the game a fair deal.  I found myself wishing that the room slots were numbered; I accidentally placed the wrong room a couple times since I pressed the number on the dice instead of the number of the slot it was in.  There is a lot of room for this to grow into something insanely fun.

Clever idea! Although mechanics seem to be a bit broken for me.

Very unique take on the theme! Love to see which direction you'll take it!  Please keep us updated in my discord! Played at https://twitch.tv/hedgein <3

This was really neat; I look forward to seeing if you expand on it in one of the ways we discussed : )

Pretty fun, you did a great job. I liked how the number of pips corresponded to the no. of enemies/dice and how you had to think about where you place the dice to not end up trapping yourself. Highlighting or adding a message like "Select dice" onto the dice hotbar when you enter the doorway might help with letting people know when they can place the next dice.

These are just suggestions and you might have already had some of this planned, but you could also include different types of enemies, or have the dice act like puzzle-pieces and not let them fit together if the doorways don't match up. That might increase the puzzle aspect and make people think more about what dice they're placing where.

Neat idea, very cool. Needs a goal of some sort, and maybe some sound.
