I love the setup. The colors are good, but the background could be a little darker. The feel of the game is that you get resources by building up mechanism/automatism in world 1 that will feed you in world 2. But it lacks dept. You got a telescope that is pointing at someones ear, when you should be looking at the stars and the endless universe. 3/5
I find all the balls useful, but I have a suggestion or two; hotkeys to upgrade (1,2,3...) and, be the first - yes the worlds first - to include a complete-button. When pressed you have everything max upgraded. I know this is very controversial, but that is what they said about the wheel too.
I suggest the ability to create a square that lasts a couple of seconds, and an option to upgrade it so it lasts longer + cool down (to increase the sense of pride and accomplishment:)
It will take much more time, than i spent answering comments anyway, but i gathered much motivation here! Thank you for attention! ❤
