Had a good day, got more done than intended. I've got some early feedback (thanks dmatter!), which led me to fix some bugs. I added the missing jump feature (wall to wall jump) and fixed a few more movement bugs (climbing into walls, etc.)

Now there's three more stages (one a tutorial only) and I've reuploaded the current version on the WoA site plus on my backup. Careful, the backup link has changed!  http://www.georg-rottensteiner.de/files/WoA5_Endurion_AssassinsrUs.zip

Looks like I'll also be able to churn out a few more stages (which as I've seen with one of the bigger stages can be quite a task)
