Oh, I finished the first two worlds, it was interesting that the first part doesn’t actually reverse gravity for the main character, then the mechanics are developed! I really liked the second part!
There were many rough edges like unfiltered pixel arts and a few bugs like walking on invisible ground at the end of World 2, understandable for a jam release - and I found out this premium release on Steam with improved graphics & animations, and I assume fixed bugs too!

You should advertise it on the itch page for people who want the full experience!
The Google play link (and other Play store links for your games in general) seem dead however. But I’ll keep an eye on the Steam releases!
