New version has birds that will drop rocks on you and destroy you in impressive fashion if you don't solve the puzzle.
Current bugs include hard-to-read equation for birds over "title texts" and also the ability for birds to spawn overlapping, also making the equation hard / impossible to read. There's also some sort of bug where the double jump triggers unexpectedly, but it's so far harmless.
Added a boost to the double jump, increases speed for a moment to make the jumps more forgiving. Also added a waypoint above the currently "active" ground puzzle. (Icon does not appear properly if all puzzles are solved and next level component hasn't been autogenerated yet.)
