I liked how the idea was simple. When loading the game, I immediately knew that I needed to shoot the boxes. The inclusion of a menu was a neat touch as well. However, the mouse sensitivity on my end made it difficult for me to aim (I'm using a trackpad). It was also hard to notice the score counter. Putting it at the center of the screen could help with that. It would be cool to see some feedback once the trash is shot (maybe it explodes, makes a funny noise, etc.) Adding a garden or some sort of environmentally friendly structure to defend against the trash could make gameplay more purposeful as well. Overall, I congratulate you on your first game jam entry! I hope that you can continue your game dev journey.

A bit rough. While I was able to run this in the browser (and thank you for making it a WebGL build), the mouse sensitivity is insanely high. I was able to destroy the cubes (trash) that seemed to spawn endlessly, but I'm not sure what else there was to do. I noticed that there was a counter to indicate how many cubes I had clicked, but I didn't see a timer or anything to challenge me other than the hypersensitive mouse. I did notice that you had some simulated buoyancy or water behavior going on, nicely done there (or maybe it was just my imagination and the water texture just overlapped the cubes). In any case, even a simple 60 second timer and a high score would at least make this feel like there is at least one more replay to be had. If you wanted to lean into the climate resilience theme, you could compare the amount of trash destroyed to the size of various real-world objects or as a percentage of the Great Pacific Garbage Patch (if you really like small fractions anyway). In terms of adding additional challenge, you could add civilian boats or wildlife that the player should avoid clicking on. In any case, congrats on the submission, as it's still more than I built for this jam.

Edit: also, congrats on sharing your first game with the world. Looking forward to what you make next!
