Great first game jam submission!
I had fun in my first playthrough but also some feedbacks concerning the balance.
I noticed that the speed increased with the progress of the level, what made you jump "higher" or "farther", helping you to jump over thicker obstacles. But my guess would be, jumping over the double sunflower at the beginning is impossible (due to its hitbox). And the triple sunflower also seemed nearly impossible with maximum speed. But since it did not end the run but rather reduced your score, Im fine with it for a jam game.
Love the little cinematic intro scene with the control scheme.
Congratulation on finishing your first jam !
