The game concept of a puzzle platformer where you can switch gravity is rather classic but something that works well and can always be extended with further mechanics. Controls & game feel overall work fine.
I had two main issues with the game. The first being the lack of indication of what the purple thing on the right side of the level was. The two buttons next to it having no prompts and looking the same as buttons you’re supposed to stand on. On my first playthrough, I didn’t understand it at all and after not finding any other ideas, I managed to go upwards by climbing on a box & switching to child (riding on the box as it went up with the switched gravity) which wasn’t the intended solution at all. I only understood what I was supposed to do after reading the comments here and seeing the mention of a catapult & that you were supposed to press E on the buttons.
Next issue is the energy system which feel a bit out of place as it brings nothing in the current version of the game. You can still do everything even without energy, just a bit slower, and I’m not sure what it could bring to the actual puzzle-platformer gameplay.
