Really enjoyed the game, however there's no way you got a 22. The best I could get was a 11 (maybe that's because I'm bad) but still. If you could attach a video of you running it and getting a score of 22 then I could believe that.

Sorry for the late reply. Here's the clip!
It took me several hours to get it this low and my friend that you can hear on the video discovered the strat at the end where it's possible to shoot the left most slime from far away. It's often those types of strats that allow such abnormally low times. I'm glad you enjoyed the speedrunning aspect too. :)
