SUB 3!!!

There's still room for improvement, but I'm pretty happy with this time.

For the record, things that could be improved:

• 1-4: You can get to the top right before the frog jumps to the edge of that platform (should save between 1~2 seconds)
• 3-4: If you move fast (and precisely) enough, you can get to the top without waiting anything (should another 1~2)
• I'm pretty sure there's still some micro-optimizations here and there, that will save frames
