Rainbow Cave Raid v1.20a is out!

This update was originally just supposed to fix a few bugs, but I decided to revisit an idea I had back when v1.10a was starting development and add a new mode!
Extended mode features 3 loops, starting at Arcade difficulty and becoming progressively more difficult! Each loop also adds some other changes, so it's not entirely the same stage each time.
I kinda slapped this together in like 3 days, so please let me know if anything goes wrong!
Other changes include a new mode select screen, a few bugfixes (the playtime counter should work properly now) and a slightly updated practice menu (game mode and difficulty are now separate, and you can practice later loops of Extended once you reach them).
