First you can try disabling animations, i.e., setting the animation speed to ‘Instant’ (System Settings → Workspace Behavior → Animation Speed). Then the launcher will appear much quicker when you press ‘Start’ / the ‘Meta’ key.

Then you can try disabling some search plugins. To the right of the search field in the launcher, there’s a settings icon. Click on it and then on the ‘Configure Enabled Search Plugins…’ button. (The name of the button is misleading; you can also disable plugins here.) A good strategy is to first disable all plugins and see if this helps. If it does, enable each plugin you need, one by one, until the search becomes slow again.

I don’t think this is exactly what you‘re looking for, but for cross stitch patterns, KXStitch can import images and create simplified designs with a reduced number of colours and cells/pixels. The KXStitch handbook gives a nice overview of all the features.

I’m surprised that Penny Pixel’s YouTube channel isn’t more popular. They create pixel-perfect parodies of old 8-bit games.

My favourite is a video of the ‘Sierra’ adventure game Joker, based on the Batman movie of the same name. But there’s also California Games 2018 (where you compete in events like fidget spinning and drone flying) and Mamma Mia! Kart Racer (which is actually worse than it sounds – don’t say I didn’t warn you!).
