Any other games like this?

Since Platago is basically dead, anyone knows of any games like this? Besides Mario Maker and Levelhead, I mean.

Hello, I haven't tried it, but maybe Platform Builder is worth it?

This is an open source platform engine I found with built-in level editor: https://glitchapp.codeberg.page/_boxclip/ It is a work in progress but you can actually create levels and games with it.
