This game has excellent tutorialization all the way through while introducing new mechanics and enemies. The mechanics themselves are explored thoroughly by using previous mechanics with increasing complexity, although the limited screen real estate reigns in the chaos. Every set piece has something unique to offer and I was engaged the whole way through.
Then the boss happened.
The UI change to just the health of the boss and myself. The boss has four phases and has I-frames, making this into some sort of SNK boss fight. The limited size of the battle means I can reasonably memorise all four phases and formulate a winning strategy. It worked, but I have to acquire a deeper understanding of how the tools work and the boss and its minions' movement patterns by repeatedly losing. By perfecting the first 3 phases. I got 10 health left on that boss. 10/10 boss and 10/10 game.
