Considering Ice Path is my all time favorite Pokemon dungeon, this game instantly clicked with me. The style thematic and consistent, and the gameplay has a great core feel to build a whole game around. Moving platforms, multi-room puzzles, boulders that need to be pushed, the possibilities are tantalizing.
Backtracking could be made a little easier, it's very easy to softlock yourself going backwards into a room that requires an ice block to reach the exit (Three Tracks for example). I was also able to enter some kind of noclip mode by mashing E on a book too fast.
Total playtime: 30ish minutes. Found all the books but couldn't actually go to the exit to gloat about it.
