I really love the graphics in this, and the concept of collecting dice that you roll to generate a platform to place is really clever!
Unfortunately, the game suffered in terms of the controls; it ended up being frustrating in terms of difficulty, and I don't think it was necessarily the goal here. A snappier control for the player would have made this a lot nicer to play -- specifically jump height, move speed, and deceleration. If you look at something like Celeste or Hollow Knight, the key to making it so nice to play is the level of control you have over the character; perhaps something to look into (I think GMTK has some videos on this as well, breaking down the specific elements).
Anyway, sorry for the essay; overall not a bad game, with the potential to be quite good!
