This is exactly the sort of game that I was hoping for when I read that the theme was "roll of the dice"! I love puzzle games where you have to figure out routings and there's modifiers to movements/placements so you can't just trace the easiest path all the time; the use of the faces for the number of tiles moved was wonderful because of how easy it communicates that important bit of information within the game instead of needing a tutorial! Most of my complaints are regarding it being too short (when I beat the last level I just sat still for a few seconds, going, "Wait... that's it? NO! I wanted more! q-q"), the first few levels being a bit too simplistic even for tutorial levels (but I'm an old grognard and comparing to when I was a kid, not kids nowadays, so may be being too harsh there?), and that the tiles/pads that modify distances don't have any visual differentiation other than just the + or - beside a number; some way to tell them apart more easily visually would be appreciated, with a mono-colour scheme like currently exists being something used in a challenge mode perhaps?
I absolutely LOVED that you could finish some levels without using all the pads, too, so while some were "figure out the exact pattern you need to move in", others were, "try to find the solution on your own", so it never got stale and always felt fresh changing between the map types. I also really liked the harp-like sounds used when moving, and how each face had subtly different notes from each other, too. Just all in all, very fun. I really hope you decide to take this game and fiddle with the visuals some, make it more your own thing, and expand on it greatly!
