Hey! For your third project, I think you have done very well in finding and managing a good scope. The game looks pretty, and the mechanics are simple yet entertaining.
One downside though, it's not optimized for mid-low range phones. I have tested on a samsung galaxy A20 and can not get over 17fps. In my experience, I've found pixel lights, forward rendering path, and fog to be the biggest culprits for mobile lag. I think you have a fantastic game as is, but you could broaden your market and customer satisfaction by taking a little look at optimization.
Good luck in your projects, and feel free to msg me if you want a quick test on older devices!
