I’ve tried Junk Store and like it enough, but I feel it’s not good for the target audience.

• The initial instructions don’t explain easily how to install it, and neither does the ad. I feel like this is crucial for people who both use a Steam Deck and want an easy to use all launcher.
• The payment scheme. I think most of the Linux community (which is used to free software to start with though) would understand a developer getting some money, but I also think most hate subscriptions. You can keep them, but I think many wouldn’t mind a single time payment option that only gets updates up to a x.99 version, with having to pay again for a version 3.0 etc. Especially for this kind of software in particular.
• It’s competing against Heroic Game Launcher.
• The name could be better. Techies will get it, but more casual users might hesitate.
• The AI art used on the website could be better if going that route.
