I have been occasionally playing this for a few months and finally got all the medals on year 376.

Good game, unlike most arcade games with endless and therefore pointless game length and inevitable death, this one had a lot of medals and various skins to keep me interested and therefore deserves a good score. It is commendable that there are a lot of different obstacle types that appear rather high in the cave so players interest is reinvigorated and it's not just the same stuff over and over again for a long time.
