Darn. I guess I will continue to squint :)
Another thing: how all the clean things stay clean after I removed 5 giant dirt spots with them? Bug? I expected them to become dirty.
This jam could be expanded into a regular-size game. You could be a person working as a professional cleaner, so in each level you clean some new settings with progressive difficulty. And it's not your mom, but your nasty boss that checks how you did at the end :)
Novel idea + nice pixel art, it could be really popular!
