This game is awesome! I really could see myself spending a lot of time playing this one. It's simple sure but honestly it doesn't need any more complexity, it's a game about speeding through a wormhole and it does a perfect job at being exactly that!
The colorful design of the wormhole and well-programmed endless generation shows that you are both very good at making games that are visually appealing AND structurally sound. The only thing that could use a bit more attention is the UI design, godot defaults tend to make a project look more unfinished. Just some simple color and font changes and I think the game would look way better.
Regardless, this is one of my favorite endless runners I've played this jam! Great work!
