Not an idler, unless you consider that you can idle for three fights before the game pause in a shop, it also stops when you click outside the game window.

The meta currency upgrades scale away too much considering the little to no effect they give as you upgrade more and more, you end up needing dozens of runs to upgrade 2 or 3 skills by a level and get less and less benefits from doing so because it's a additive bonus.

The boss fights rely too much on dodging the skill debuffs, making the relic that does so a necessity and upgrading it can fail requiring more and more runs.

Having to click and buy swords, shields and regenerate stamina on every shop (every three fights) dont make this game any fun.
