Hey Roger! Fellow KFBF/game dev hobbyist here! So keep in mind with my feedback, I only have one more game under my belt than y'all, and while my second game felt way better, my first one was nowhere near this nice!
This is a great first game from you guys! The art, sound design, music, and vibes are all really good. My biggest piece of feedback would be to look for ways to add more "feedback" for player actions. The gameplay loop makes sense and I like the progression, you can really feel the upgrades increasing your energy generation, but clicking the buttons don't really feel "meaty" enough, if that makes sense. Also it would be great if once you click the sun to trigger wind, it had a visual change, whether that be just a color change during the cooldown period or an actively updating cooldown graphic, just to help with gauging the timing of the wind.
Again, these are small nitpicky things, overall you guys did a great job! Would love to get your hands on my entry if you have a minute or two!
