Very fun game--took me a little while to get the hang of it, but once I did I really liked playing it and ended up losing track of time playing until I got "Game Over". It's a fun puzzle, and I really enjoy how the different objects react differently (like the exercise ball being bouncy, and you bouncing if you jump on it).
Some minor quips: at a certain point it got to where I was kind of waiting around waiting for trash to fall, because I had built a really stable, wide base, but things kept tumbling off the sides and despawning at the edge of the game before I could get them, preventing my pile from getting much higher - I ended up finding that the most effective strategy was staying at the top and grabbing things out of the air as they fell, which, while effective, wasn't super fun after the first few grabs.
Assets & UI/UX:
The audio is good, all of the trash and character assets are really nice - the UI, as a result, kind of sticks out like a sore thumb. I think it probably would have been more visually appealing without the bounding boxes behind the text? If needed for legibility, a low opacity black bounding box might be less intrusive. Additionally, it would be really nice to have more info available in the UI about certain things, like what the difference is between the two game modes, what certain power-ups are actually doing (it took me a little while before I realized that's what they were, and I'm only 50% sure I know what they do). Would also be nice to have the controls listed in the game somewhere, rather than just in the description (A/D is easy to figure out, but it took me a while to realize I could jump, since W didn't do anything). Having a pause function is a really excellent choice, I appreciate that you incorporated that.
Overall - I really enjoyed this, and I'm glad it came up in my queue. It's very clever and feels great to play. I hope you expand on it further, maybe even incorporating more levels with different types of objects and powerups, rather than a single level with moving goal posts. Great work!
