Had some trouble interacting with the game. Mouse-look is a bit awkward and hard to point at stuff. To buy stuff it seems like you don't know what you but until you got the funds for it, then you press buy and the cost is reduced, then you cant use the thing directly, you have to close menu, then reopen it and press the flower then place it in game and press "E". Still it just changes color a bit when placed, but there is a non-stop animation of three coins falling over and over again. Not sure how to proceed from here.
