So, the blink seems to be more trouble than it's worth.
I had to design levels so that certain bugs with blink wouldn't allow the player to skip most of the level.
It gets annoying when you accidentally blink while moving around fast (and it looks unprofessional).
More bugs are surfacing, such as being able to blink through walls where a ladder is just on the other side.
It doesn't really seem to be useful.
Should we throw the blink ability out?
