I really liked the color palette and the wall-climbing. Especially the way you fling yourself forward when climbing over a wall. That was satisfying! I got stuck in a couple of parts including getting stuck off screen at the end of the first level (trying to go over the wall instead of under it.

I think it could stand to have the speed turned up a notch, but still fun all the while.

I liked  the game a lot. Apart from the platforming stuff, you have implemented a more than an adequate crawling mechanism on yellow(gooey substances) and also the air bubble pushing the player to certain directions. The music gets in the way, pounding harder in your ears than needed, perhaps a volume control to control the Music volume would be cool. Overall a nice looking game. Keep up the good work .

[Just a query, have you used "Godot" to make this game?]

[If you have completed this game in Godot, then you should export your game in HTML5 as well in a separate folder and make sure that the .html file is named "index.html" and not "<game_name>.html" Once it is exported in a folder, zip that folder by right clicking that and choosing "Send To > Compressed (zipped) folder". Once the zip file has been created, upload that to itch.io and check the option "This file will be played in the Browser" and set the "Viewport dimensions" to the dimensions you have set for the game. Additionally you can check the "Mobile friendly" and the "Fullscreen button " options to get your game working in the browser as well. Instead of the "Infex" image shown currently, your web version of the game would be shown here to play with a "Run Game" button in the middle. Also add at least 3 screenshots of your game, as visually its quite good and you should add them as well.]
