Very nice and simple game you've got here where all of the elements of it come together quite nicely. The main feedback I can give is maybe add some better indicators for the shop building/crafting like maybe an outline of whatever object your attempting to place down on your cursor? Or something akin to that. Other than that the main thing I think that'd be best for the game is to see it expanded upon and fleshed out from here. Great job on the game and I wish your team well on it if you continue to develop it from here or if you choose to do something else, either way, good stuff!
