Alpha 6.1

Hello! Alpha 6.1 is ready. The changes are:

• Bouncing off corners won't send you off in a seemingly random direction anymore.
• Fix so you no longer bounce off the sides of one way platforms, and now pass through them as intended.
• Experiment: the pullup ability is disabled. It was happening on accident too often and maybe wasn't so useful in the first place. I might  later make some adjustments to jump height to compensate, but for now everything else is the same.
• The down slam ability has been re-added.
• Glace no longer appears behind one way platforms sometimes.
