Tell me about YOOMP

I just rediscovered YOOMP, a fun little polish game from 2008 for the and now hold your seat Atari XL line of computers.
Just played it yesterday again, it really is fun, it is a hybrid of
3d action platform and rhythm game with a mild techno music score.

Played it an hour yesterday, after having to figure out for 30 minutes on how to start it on the mister.
Fun fact btw. it is one of the titles integrated in the Atari 400 mini computer just released!
