It’s been mostly Isaac as usual but I picked up Shotgun King: The Final Checkmate yesterday and I like it a lot. It’s a fast-playing roguelite with a neat idea that’s implemented well. The game mechanics remind me of Hoplite on mobile.
The game is currently on sale and has a free demo. It has good controller input and low resource use, a great fit for the Deck.
Any naming convention is fine as long as it’s meaningful to you. But it’s a good idea to keep your own repos separate from the random ones you clone from the internet.
