End up with 3087!
You built a pretty good game using cubes, and the game mode is also very interesting.
The losses don’t feel very serious right now. The score loss from time passing and jumping is not very obvious. When I gain points, there is only a sound effect, so I think you could try adding more visual feedback to make both score gains and losses stand out more clearly.
I also tried imagining this gameplay in 2D, but then I realized that this 3D version is much more fun than a 2D version would be.
Congratulations!
