This game is a hardcore puzzler, but because you also have infinite redos on moves (all the way to the start) for every level, it’s also somewhat casual. Therefore, it hits that sweet spot between hardcore and casual that makes a game addicting.
Quick list of good, bad and neutral:
+randomly generated levels
+you’re a dog trying to save your elderly master! Isn’t that cute?!?
+learn-as-you-go type game — no tutorial, yet patterns and mechanics are extremely easy to learn due to redo button and this gives the game a sense of discovery, similar to Road Not Taken, another game.
+offline, fully premium, zero IAP
+flawless controls
+PC port. PC quality.
+does not make device hot
-drains battery fast
-not a portrait game. Bummer.
-level 15, the final level, is exceedingly difficult. It can only be done with full hearts, both a healing potion and a bomb, and some RNG enemy placement luck. Frustrating.
~while levels are randomly generated, there are boss levels that are similar enough to each other for you to notice. Might make it repetitive for some.
~infinite redos, but if you die three times, a ghost comes to kill you. You can’t make quick moves, or you might die. Once you die three times you start over.
Tip: you can swap the start and finish points. This gives the game even more depth.
