Yes, it's only the tip. I didn't think the art needed to be that large until I thought about it, but then I didn't want to make the section harder than it was before art, so I kept the hitbox size. I already know that section has several issues (which I'll fix after the jam). As for the last section, it's definitely harder to play with a trackpad, which I actually never considered, so thanks for pointing that out! But remember, you can dodge the arrows by moving left and right with the platform, which should make that section possible.
Thanks for your feedback!
