economy is unbalanced and moving things is genuinely unenjoyable. I'd suggest you look to games like yours that have implemented movement in a more enjoyable way. Project P.I.T.T. is a good example

also theres a lot of things or upgrades that are to expensive to what they really do + it gets kinda borring

pt: you have to pay 1 million
