This was a really fun concept, and the mechanics were pretty simple to get an understanding of!
The wall mechanics were pretty glitchy... lots of clipping through walls, and there were times where I just couldn't draw walls anymore even though it didn't seem like there were that many walls? It might have been better to make the wall drawing more restrictive so it's more stable - for instance, instead of drawing freehand, the player draws lines (which you could do by scaling rectangles instead of tons of dots), or just restrict the whole game to a grid.
It would also be nice if there was a countdown at the start of the round, just so the player has time to visually process what's going on before the debates start happening.
Really good job with the concept!
