There was a skip tutorial button, though I didn't click it, but yeah, the tutorial was shit (Barely explained anything), and the game isn't worth it.
Only way to progress is through Super Nymphs, which you buy with Hearts (The premium currency); cuz they're the ones that deal the real damage.
Everything else's damage is just really poor, unless you level them really high, but the coin gain is just too low (At level 5X you'll only receive 5~6k coins per kill, but you'd need like 2+mil to level the lower end Nymphs to max.)
