Godless Night doesn't work on Helion (Arch Linux)

[aboutafter]

Sorry if I'm screwing up and this mod should not work with Helion. I just wanted to try it on it because I have very poor performance on GZDoom and Helion would be the perfect way to play it.

https://www.doomworld.com/forum/topic/141009-godless-night-gzdoom-episode-rc1-11292023/

I tried with version 0.9.4.0 and 0.9.5.0.

If this mod can't run on Helion and it's not a bug, sorry!

I'll let @nstlaurent reply in more detail if he likes before closing this, but this appears to use features that Helion does not support, including both ACS and ZScript.

Helion is roughly at parity with ports like DSDA-Doom in terms of what it supports--Boom and MBF mapping features, DeHackEd, and a few bits and pieces of DECORATE needed to support the MBF21 standard. Support for the id24 mapping standard is Coming Soon™.

Helion does not support the full set of GZDoom mapping features like 3D floors and slopes, does not have full support for DECORATE, and does not support ZScript. I believe it also does not support Hexen features like hubs, polyobjects, and ACS.

Indeed, Helion does not have the level of decorate support or ACS/ZScript required for GZDoom mods.
