Absurdly fun. Other than some bugs that caused me to go flying straight up sometimes, everything worked great. Managed to break the 70m barrier!
It does feel like the number the dice lands on should do something (does it do something?). E.g. give you a random effect for your next throw? That would work really well in terms of scaling with the dice size upgrades (putting better effects on numbers the smaller dice can never roll), which also don't seem to do much (I expected a lot more roll on the e.g. d12 than ended up happening).
A very enjoyable game. Well done!
