Two options off-hand: Paradox’s in-house games are all linux-based. Unity does linux as a compilation target, but I understand their reputation isn’t great, and may limit their ability to take interns. Hope you figure something out!

I had the same problem, and never cracked touch typing, because my brain kept going back to the old, faster way.

I finally cracked it by learning a different layout while only touch typing. Maybe that’s a way to go if you want to get there?
