Really polished game! Love the art, visual effects and the sound design! The mechanics are creative as well. Jumping, dashing and moving feels responsive and precise. Id say one thing that you can improve on is the background. The foreground is clear but it would be better for the background elements match with the atmosphere. eg having to trees more blue as you get further. Other than that, had a great time with this one. Impressive for your first game jam submission!
