thanks a lot for taking your time and writing the detailed feedback!
I‘m glad to hear you liked it! I‘m still pretty early in development and the feedback is really valuable.
My biggest issue is the simplicity and lack of depth as well, I wanted to test out the mechanics for the skills first, before diving in the detail.
Are there specific upgrades or ideas you can already imagine that I could integrate?
My final goal is an extensive crafting/production and skill system that interlocks all systems!
