Thanks for the pointer!

For anyone else wondering, I found that    Neutralino.app.exit()    works for Ct.js's default app exports

By the way, I was wondering how you created a menu option to close the game in the full version.

I assume it's simple but I can't find it anywhere in the Ct.js documentation

I really enjoyed this, nice work!

Thanks! I've emailed you from md--------@gmail.com

Thanks for the kind words! Posters are a great idea! I've added a ZIP file with a few different designs to the main page. 
Just let me know if you want another resolution.

Thanks!  Re: wall climbing and one-way platforms, this builds heavily on the default platformer template included in Ct.js, though I did modify it quite a bit.

This is a standalone app, but you can extract the PK3 addon from the ZIP. If you do that, you should change a few settings:

• Turn the Nights hoop draw distance to infinite (or set it as high as possible)
• Turn on the crosshair. This will help you land in certain levels. The crosshair will display as footprints when you're looking downward in first person.
• I recommend binding JUMP to the left mouse button and SPIN to the right mouse button, as you can press these more quickly than keyboard keys. Keyboard and mouse are recommended.

These settings are on by default in the standalone version.

The PK3 is in the ZIP under /srb2/tailwinds/srb2/addons/tailwinds-core.pk3
