You can indeed run Intersect on a Linux-based private server. You will have to do the editing, however on a Windows machine since the Intersect Editor does not work on any system except Windows. I did this for a year with my game and it worked, fine. I just uploaded new versions from my Windows desktop to the Linux server, as necessary.
 
Basically, here are the steps:
Create your game. Upload your game server to your Linux server: Usually, this means you will put the game in a ZIP file Upload the ZIP file to somewhere on the web. Use WGET to retrieve the file Use the Unzip command to extract the files to your Linux main directory Make sure Wine is installed on your Linux machine Using Wine, open intersect client.exe Your server is online Hope this helps.
 

The thread above is one of many discussions on this subject. You can absolutely utilize some sort of encryption when source is available, but there will always be a chance that people will access your files, regardless. Read through some of the treads on this forum about encryption and maintaining proper ownership of intellectual property for a long answer...

Short answer - yes you can protect it, there will almost always be a way that people can get access to your files if they really want them, regardless, but game development is so inherently  difficult and more than the sum of its parts that it shouldn't keep you up at night if someone takes your art and attempts to make a game of it. tl;dr: If you wanted to steal an artist's painting, you'd need to do more than just swipe their paints.

Was able to replicate this in my own game and can confirm projectiles act like grappling hooks against blocked spaces. I would post this in bugs.

You can do that, as Kibbelz has said, in the Common Event Editor. Go into that, then:
Down in the left hand side at the bottom, select "Level Up" as your trigger. In the Spawn/Execution conditions button, you can choose 'Level is'... Then 'Equal to'... and input '10'. Then you will write what you want to display on the player screen or chatbox in the commands field. You can also run a Conditional branch directly in the commands field. which checks if the player is 10, but those can get messy if you want multiple level up events. If this is specific to the player's class, which it seems to be, I would add another Spawn/Execution condition of 'Class is'... then select "Adenturer". If you want to get right to the point, you could even do 'Show options' to be prompted to change class, directly. However you do it, hope this helps.
