Some copy/paste reply included: I definitely spent way more time on the look/feel/sound than on the gameplay. I always fall into that trap. For the perspective issue: Yeah that's fair; I too felt like this was bordering on a rage game instead of a cozy game based on that.
Yes, I wanted to make the cube bois be a slingshot-like drag mechanic but ran out of time, so those break the rules I set, unfortunately.
Catching the spheres are easier when you use the triangles to bring up the protective walls, but if you never click the triangles, you'll never know that's what they do. It would have also been good to have the click collider larger on the spheres because it is just too hard to click right on them.
Thanks for the feedback!
