I have a new update available for TheXTech PS Vita Edition.

Fixes in this Version

General improvements & updates from the devel branch have been merged into the Vita branch.
- Additionally, Vita has officially become a first class platform for TheXTech.
[ds_sloth] Objects, layers, events, most strings are now represented by indices which saves about 5mb of RAM!
[Wohlstand] Sound & Music improvements in SDL_Mixer_X
Through the configuration file, the following gameplay additions can be enabled:
- "Show Collected Stars Per Level at World Map"
- "New Editor" (WARNING: Though it does render 100% okay on Vita, the controls are rough and need to be specialized
  for multi-touch devices (instead of just reading SDL's mouse API for rough touch events)
- "Show Episode Title during gameplay"
[VITA SPECIFIC] Vita renderer adds support for drawing un-filled rects, useful for Editor and other misc. new features.
[VITA SPECIFIC] Ensure all point normalizations are done against the Screen resolution instead of current viewport resolution.
[VITA SPECIFIC] Instead of mimicking glOrtho via a CGLM ortho matrix, we are now normalizing all drawn coordinates to -1.0 -> 1.0 (from screen space to OpenGL coordinate space) Before drawing.
- This has FIXED the floating point imprecisions that plagued the game early on. Backgrounds now stay stitched together.
[VITA SPECIFIC] Fixed renderRects permanently, ensuring that even the most miniscule ones (Pause screen) are drawn 100% accurately and correctly.
[VITA SPECIFIC] Removed copywritten material from the livearea (just in case).

Overall, this is definitely an update I recommend for the fans of TheXTech playing on PS Vita. You should see more a more stable, and more true to form gameplay experience.
