Picked up for Android - a breath of fresh air as a free game amid all the shovelware, and very high quality for being free. Fundamentally a time looper with permanent progression that you can unlock in the form of skills you can buy and (persistent) equipment you can acquire. Unlike most time loopers, though, unless you reach one of those milestones, the loop gives you nothing. This does mean that you can't just grind your way past walls -- you have to optimize, or sometimes change your approach to work on an entirely different goal instead, and it's never really clear if you're chasing content you're not capable of solving yet. I got to the level 2000-3000 area before hitting a point where I had gotten most of the achievable medals and unlocked two tiers of equipment, and have spent a number of runs unlocking nothing new. The game might benefit from a hint or quest system giving you a suggested next quest, or more feedback about statistics/builds to make it clearer if you're playing suboptimally, or perhaps some minor guaranteed loop bonus.

Tl;dr: This is a solid game and I recommend giving it a look, but as it is it's a bit too roguelike for me with a lot of trial-and-error gameplay. That's not a turnoff for a lot of people, but I'm not certain I'll personally be able to finish it.
