It is an amazing game. I like the mysterious mask idea and tabbing to switching between reality and mysterious space. The game length is appropriate. It takes some time for me to discover the mouse is navigating both the facing direction and the sword, and even it shows locked door, I can still press space when I have a key. Boss fight is a plus for this game. The ending screen is a bit simplified when compared to other parts of the game. I hope there may be a change of background music in the boss scene (although switching between reality and mysterious space may make the background music transition annoying), and when the entities casts spell or the boss spawning enemies or attacking, there can be SFXs.
