Hey CandyHen!
I think this is one of the best games where it can be expanded into something really special if you wanted to develop it!
I think it was satisfying building your own wheel. Following up with what Valeriy Petrov said: I think you can make the wheel more dynamic by giving more synergy where you place upgrades, though I did see that lightning got extra from other lightning placed adjacent. I think there should be more of that!!! The wheel is kinda your loadout, and I could see a lot of options for adding meaningful decisions for where you place stuff.
That said I had a great time playing, and I hope to see this developed further in the future!
