I keep getting a "Failed to load mono" notification and can't open the game, any way to fix this?
That error is specifically the Unity engine failing to start, because it cannot find the mono.dll that is inside the Mono directory.
One possibility is that you could have the exe file located in a different directory from the associated Mono directory. Always make sure to copy all of the files from the archive to the same directory on your machine.
Alternatively it could be something strange in the path to where the game is stored. For reference: https://answers.unity.com/questions/1413411/fail-to-load-mono-on-a-built-project...
If you had it installed via the itch client, then I'll have to do more investigating.
Sorry for the late reply. I've downloaded the game off of Itch.io, and have everything in one folder: Mono(folder), DinosauriaAlpha2Win_Data(folder), the Dinosauria application to run the game, the Unity crash handler, and the unity player. Is there something I need to move/change? That's how it came downloaded.
It is supposed to just work so long as all of the files are in the same folder an a computer, and that computer meets the minimum requirements to run Unity: https://unity3d.com/unity/system-requirements.
Alternatively you can install the itch.io client, and download/play Dinosauria with the itch.io client.
I am not familiar enough with the error to remotely troubleshoot.
