I love the cute world and the relaxing BGM—they fit together so well! However, I got a bit stuck and couldn't figure out how to progress past the second gimmick bro;; Still, great job on finishing the game!
Where exactly did you get stuck?
I think it was past the trampoline. I got a item that looks like tospeed booster, but I had no idea how to progress from there.
You can read about the controlls in the description, it probably was the dash you picked up, so it should work with the left mouse button.
