I’m just coming back to say how much I am enjoying this game. It’s a perfect PlayDate experience. I love the puzzles and the different abilities which work really well. It’s just the sort of game that I purchased the PlayDate for - it reminds me of the classic BBC Micro game called Citadel. If I was to quibble, I would say the music is its weakest component - the tunes are a bit sparce and repetitive. One other frustration is the long walk from the save screen to the boss battle in the west tower, which I am currently struggling to beat. Every time you die, you have to work your way back through the same four rooms just to do battle again. It gets a bit frustrating. Two small criticism on an otherwise excellent game.
UPDATE: I finally beat the boss and finished the game at 99%. No idea how to get the final 1% which is going to bug me!
