Thank you for your fast and thorough reply! Warms my heart seeing developers like you!
I had most of my trouble (which I can recall) at level 8.
The following breaks the screen and causes the level to restart:
- start>w>w>fail
- start>w>d>s>fail
- start>d>w>a>s>s>s>d>s>d>d>d>d>w>w>d>fail
- start>d>w>a>s>d>w>fail
- start>w>a>s>s>s>s>s>fail
(are these because I slam myself into the wall? If so, in other levels it works just fine. Perhaps the level can not be solved with these steps, and so it restarts? Can't tell, but I figured it was worth mentioning, since I found it a bit frustrating considering I can just backtrack my steps)
Teleportation bug:
I can not seem to recreate this, but at one playthrough I teleported constantly between the bottom left purple teleporter and its link at the other side.
Again, REALLY good game. I enjoyed every second of it. Thank you!
