This was short and sweet.
I like cartoon animals and the main character is a good one. I like how expressive is its face in the “cutscenes”, good job there. The graphics is nice, the only thing I would criticize is that there are multiple graphical styles that don’t fit that well together: the pixelated main character, the cartoon background drawn with straight clean lines, the landfill being just a pile of icons.
I feel the theme is kinda forced. The main focus of the story is on returning back to the old ways, that’s not really repurposing I think. The mechanics are more fitting, though in the end it was just a platformer with more-or-less ordinary abilities.
I had issues with the controls. The window for sticking to a wall is quite tight, I couldn’t reliably hit it (in contrast with the other abilities that are very forgiving). I would recommend to make it so that the player can hold a button and the character will stick when it comes close to a surface automatically.
Another issue was that I did go out of bounds several times, even without trying. (First time was in the sewers: I leaped over the trash pile, expecting to hit a wall, and had to reset the level instead.)
I also kinda dislike how the walkable roofs are not slopes but stairs and require constant jumping.
The chewing mechanic, though thematic, doesn’t add anything to the game, I had always plenty time to rechew my gum between ability uses, no rationing or tight timing (though I probably wouldn’t like high difficulty here). Too bad the chewing sound is the worst and most annoying in the game, as the chewing is the most frequent action.
At the end, I really hoped there would be an easter egg, that I could turn back and return to the forest, with a short cutscene showing my character chilling with the clock on the wall and under the radioactive lighting :-). Instead, jumping to the left got me out of bounds again.
Edit: forgot to add note about accessibility: the game is a very visual, it wouldn’t make much sense to add any visual-impairment-related accessibility options. The completely missing options are a problem though: I would like the ability to turn off the sound effects. The credits are problematic too, almost unreadable in the default window size. You have a lot of blank space there, use it!
