Wow, that idea is seriously awesome! I'm totally digging the mechanics and, man, the aesthetics are just so cool. Here's a little suggestion: sometimes, when I'm in the heat of battle, I get so caught up in thinking about the enemy's health and the dimension I'm in that I completely forget to keep an eye on my stamina. It'd be super helpful if there was, like, a text that pops up or some kind of indicator that really stands out, you know? Just to remind me when I'm running low on stamina. But seriously, great job overall!
