After roughly 4 hours of trying to fix alignment issues since my building blocks aren't the same size and allow for proper snapping, it now works! Different block sizes, rotations, and colors. Now I just need to add the other blocks like rounds and corners.

The hardest part about my game project so far has been trying to finish the terrain generation, but I'm almost there! Although I spent too much time trying to get different slopes and blocks working. I had to scrap it for now.
