GDevelop is actually a really nice engine to use! It has a great visual scripting system and is truly free, without the limitations you get with Construct.
As for the game: really fun! It’s a nice loop-based game that would also work well on mobile. I did have some trouble understanding how to catch the lightning, maybe a few hints to show when it’s about to strike would help. But after a while you get the hang of it, and it becomes fun to figure out. Unless it’s completely random and I somehow unlocked prediction powers haha, but I hope it’s not fully random!
Really enjoyable overall, great job!
