quite nice game!
i have to say the tutorial was really good at the beginning.
i think later on a bit of a more gradual introduction to the game's complexity could've been good, but i did end up playing all of the levels!
i really like the design decisions you made with animating the tiles that match the pips on top of the die. and that they represent well what they do once you're on them.
adding the map of the cube was a great idea, some games overlapped it onto the tiles, which might not have worked greatly here, but is preferrable if you want the player to know where they can move.
i think adding some music, any music really, would've been a good idea.
it feels a bit empty without music.
the sound effects are nice, though they don't seem to always play, and the visual design is quite nice.
great job!
