Nice game, I especially liked the chunky upgrade dice! With the energy mechanic, I was almost expecting there to be discreet levels that I chipped away at each run, with some kind of incentive to complete each level in as few moves as possible. I like the idea of random upgrades, but I didn't feel like I had to adjust my playstyle at all to match what upgrades I ended up with. Also, it was hard to tell if I was destroying enemies or if they were damaging me. But overall, I liked the core mechanic of trying to carefully pick my way through the cave with limited moves, avoiding enemies as best I could - my favourite strat was to just plow ahead and use up my energy before they could catch me!
