Levels for kids or by kids

I propose we use this thread to mention any levels found that would be well suited for young kids. It would be hard to put an age identifier on the category as they all mature so differently, but let's keep it to Age 5 and below, or definitely no more difficult than the original levels which most of the kids by 5 would probably be able to do anyway. Of course any levels created by kids automatically qualify.

Here are some great examples to start us off:

ALBUMS
1-Tap-Win series by @Chuckthulhu
Mekorama for Children series by @S. Nagy
Kidthulhu series by @Chuckthulhu
Yoyo levels (5/6 y.o.) series by Yoyo (posted by @Gepeto)

LEVELS
Suck Up by @Khudrat
Sweeper by @Astral_Mage
Playground Pain by @Lary

Also, you can find more levels for kids by using the 4kids tag!

 

I found another 1-tap-win level that very young kids may like: -R- Factory, by @Mauro77.
