Thank you so much! I'm happy you enjoyed it this much! ^^
I put a lot of effort into making the story progression feel natural while also introducing characters / concepts without having these feel forced. And yeah! Some characters badly needed a redraw / redesign. I still have a few in mind, but the most urgent ones have been taken care of!
Goblin's Yoyo Heartpower isn't an easy one to use, but it's very powerful. You have to right click again if the Yoyo hits a shape to have it rip through it (you can hold right click to keep going too!). The line deals damage too, and once enough shapes have been hit by the line in one go, you'll be able to shoot a laser when winding back the Yoyo. Tough to use, but it can let you destroy even the strongest shapes very quickly! I still need to add actual explanations for Heartpowers, among other things.
I'm not too sure I understood your last request about Gob though! She might get an alt costume if she wins one the Patreon alt costume polls, but it'll be some time before the next one :B
But yeah, I'm glad the game resonated with you, thank you again! I'm curious to hear about the parts that caused you some issues too, of course! ^^
