Nevermind I just noticed that you don’t have a mouse. Uhhhhhhhhh. You could always grab a gameboy-advance emulator and enjoy some pokemon or Pacman Collection or Beyblade V-Force or Sonic Advance 3. Loads of classics that don’t have overly complicated buttons. I bet you could emulate other old consoles too, the Sega genesis had a phenomenal library that should all be easy enough to play on a keyboard.
