That was fun ! Pretty cool level design, and great portal-like aesthetics ! Sounds are quite cool too, especially the narrator, but there might be some mixing problems, some effects are way louder than others, and the first time I used the green face, it was like a jumpscare
I find the concept original, but I don't think it is really used at its advantage, the dice feels mostly like a clunky way to select powerups, it's your level design more than the concept itself that make it interesting. That means a lot about the quality of the level design !
I got a bug at some point, where the cube disappeared, I think it happened because I managed to grab it during the death animation.
PS : I love your videos, you taught me about so many little unity and C# tricks ! I did not know you did game jams, that's awesome !
