oops i set up the movement cancelling teles wrong. fixed and updated link in OP.

also discovered and removed an out of place text popup i found on jump 14, and fixed a missing stage number decal

another small update, hopefully the last

- made all the walls reflective again. idk why i thought nogrenades was a good idea, sorry about that
- added teles at the start of each stage that take you back to the end of the previous stage
- lowered lightmap scale (higher quality shadows)
