Timer would make it better for speedrunning this game. Will it be on speedrun.com ?

Stage 12 showed me that there must be some mechanic I didn't understand yet (or that the physics are inconsistent), because the trajectory I get after jumping from the start was different every time, and most of the time not enough to reach the next platform. what am I missing?...

I really like the music in the game, but I haven't found any source for the songs, since not many people know about the game. Is there somewhere I can look to find some sort of OST for this game?

...that this game doesn't have "very positive" reviews. :) It is a tough game but never felt like it was being unfair
