Excellent use of a dice rolling mechanic, having to gauge your jumps based on the power on the die is a killer idea, it kind of turns it into a puzzle platformer, with added urgency of the lava rising
I also liked that there was a line indicating how high the jump was gonna be, if I understood that line was what that was! The mouse sensitivity was a bit high, would have liked to be able to adjust that, but as a proof of concept it's solid!
