The camera is in perspective mode, and all sprites are rotated 30 backwards on the X axis. Similar to what some Nintendo games did I believe :)
Thank you for your answer! I’m working on 2.5D rogue-like and I couldn’t get the right transform for the camera and sprites. I just started noticing this rotation method for the sprites on the shadows, but I wasn’t sure about it. I wish I had this info before 6 months, when I started working on my 2.5D style game (website). Thanks again and good luck for the GMTK 2024!
