Just completed demo for under 20min. Very short, but seems promising and interesting concept. definitely felt big progression on some points which felt satisfying, would be happy to try full release!

Some things bothered me a lil bit was, I wanted to buy first upgrade after first try, and upgrade nodes moving around looked cool, but slightly, yet constantly annoyed me.

I'm ok, actually felt good with purchased upgrades piling up and going up (literally), but I also prefer same type of upgrade stays in same place. Node moves when that type was sold out might be okay in my mind though.
