Thanks a lot for your feedback, GGG. Every comment really matters to me and helps me understand if I'm moving in the right direction. By the way, about the upward boost - it's already there: just hold left + right arrows together. I thought it felt intuitive to do it that way :)
Yes, I'm making the game in Godot 4 and I do plan to release it on mobile too. But I also really love the idea of web games, where anyone like you can instantly jump in and test without installing anything. For now, I'm just trying to find the right direction for the game's growth
