Do you have the navigation bar on? I also set it to not hide automatically.

I also really liked Ender Lilies/Magnolias.

Other metroidvanias I've really enjoyed that haven't been mentioned yet are Blasphemous and Vision Soft Reset.

Blasphemous has a really cool theme and is pretty challenging.

Vision Soft Reset is more indie and probably PC only. It has a unique twist to the formula.

Thanks for giving us a home! 🎉

If you're serious about it, you can try to snag a DreamPi kit from https://dreamcastlive.net/shop/

They also organize game nights and maintain a list of playable games and game server software.

The main problem is the game had to support it, and only a handful of games support the broadband adapter.
