Is there some kind of bugtracker somewhere? I tried to start the 0.8-linux demo and I was able to see a loading screen but after that it crashed  to desktop with the following error:

Unhandled Exception:

I am running on a Manjaro Linux with the 5.6.2-1 kernel and the open source amdgpu driver.

Hey! Sorry to hear that. I'm no linux dev and have very little knowledge. That being said, it's questionable whether I can fix the bug. I rely on the MonoKickstart made by other people and of course the framework MonoGame itself. 

Have you tried installing the Mono framework (mono-runtime, mono-complete) and run it manually without using the "Kick" file?

Sadly the error doesn't tell me that much, there are a lot of instances in the render  function :/

Hi, installing the "mono" package on my system helped to start the game (even with the Kick file). But unfortunately it's still not really running.

I can create a character now but when I start the game I only get a black screen. Also when changing anything in the configuration leads to a black screen even before the character generation/selection.

I tried some different start options (different LD_PRELOAD paths, start Kick, start Mystica.bin.x86, ...x86_64, Mystica.exe with or without mono) but nothing helped (but I was able to always reach the menu and get into the "black" game - sounds and music were fine and I was hearing sword sounds and so on).

So installing mono definitely helped, but not enough. ;-) Maybe you have another idea? Which mono version are you using? I have mono 6.4.0 on my system.

Thanks anyway for your quick answer!

Sure! For me using the Kick on Linux works fine. I have no idea man...

Have you tried running it via Wine?

The linux version doesn't run within wine.

I tried the windows version with and without wine and I have the same error like in the linux version (so only a black screen in the game). Maybe it really is an issue with the mono version that I use. On which system did you successfully test the linux version?

The latest version of Ubuntu always works for me!

Ok, I tested it inside a virtual machine with Ubuntu 19.10 and there it worked. I also didn't need to install anything.

So maybe it is some kind of missing/wrong-version library in my host system (Arch Linux and Manjaro Linux usually have newer libraries than Ubuntu).

Something that you can enhance in your game: add statistics. How many deaths (maybe even why)? How many of each enemy killed? Playtime total? Maybe (if it exists) playtime per dungeon/chapter/...

This is something, where players could compete with each other ("I have been faster/without deaths/...")

With these statistics you could als implement achievements in the game (like "Monster hunter" - "Killed all enemy types", "I hate slimes!" - "Killed 1000 slimes" and so on). Achievements are a big factor for replaying a game.

But this was just a first thought about your game. I now have to enable the sound in my virtual machine to really play and test it. xD
