Thanks, I plan to remake this game in the future when my coding skills improve, with everything you've said. Building was originally supposed to be a feature I just forgot to add it, and the pixel snapping to the grid, if you are talking about the mouse, the reason it does that is due to how I made it an object to make it the same size as the rest of the game no matter what the window size is to make all the pixels the same size, and because of that it gave it that weird snappy feeling. But yeah, thanks for the feedback!
