Nice work on making a complete game for your first game jam and only learning godot for two weeks! Definitely have a good grasp of the fundamentals and can make even bigger games from this in the future.
Small feedback I would have is it would’ve been nice to have a hotkey like “R” to restart the level rather than having to press the button. That would’ve made it easier for me to keep retrying every time I failed. My highest score was 2229, but even that was quite tough for me to get.
Nice work and hope to see more games from you in the future!
