Enjoyable enough for a few runs, but in the end there's very little variation in how a run goes. Since you keep set bonus from heroes you upgrade and set bonuses are super strong, you wind up not caring who's in your team and just collecting for upgrades. It's also incredibly difficult to parse what's actually happening in a battle since there are no stat breakdowns (not even at run end) and damage numbers frequently overlap... which means it's hard to diagnose how to improve or even if you're doing well. Difficulty starts off laughable, but does increase to moderate levels as you get to the highest levels so it won't be autowins anymore.

In the end, if you like autobattlers, it's worth a look, but probably won't sustain you unless you're a die-hard chibi fan. Strategy is pretty limited and could really use help in the form of equipment or a redo of the collection mechanic. I'm curious to see how the sequel turns out, hopefully it'll be a bit more robust. Buy on sale if you're curious to try it, but don't expect much. 6/10
