Bloop is supposed to slowly move towards your cursor. There is a lot of inertia on purpose, but I should add some VFX or any kind of feedback to show how it works.
Can you record a video or a GIF of the minigame, showing your cursor? This may be a bug!
As for the drawing minigame, yes, I will add a highlight on the lines that aren't completed after some time! I'm increasing the priority on this improvement hehe.
I'm glad you like the game! It was very fun to make.
