Minimal feedback of what things do, exponential scaling trees (+40%, +60%, +1000%), little inference
Numbers go up, get more things, pack them tightly, not too clear how to have an impact outside of that
To some degree probably also how the tree is laid out - explosive upgrades mixed with fireworks, cooldown randomly put behind a heat upgrade
Chaotic is certainly accurate, little cohesion
Would be nice if heat could do more eventually, I'm sure that's planned - becomes a little arbitrary and not important until the ending after not too long
