Hey DK! That's a real bummer you're having this problem and I'm so sorry to hear that. :( So the file that's said to be missing (UnityPlayer.dll) actually comes in the .zip file that Buddy Simulator comes in. So it's odd that it's supposedly missing. I would first re-extract the .zip, then try playing again. Also make sure the file UnityPlayer.dll is in the game's folder. Once again, so sorry that this is happening. If there is anything else I can help with just let me know. I'd feel really bad if you can't play, especially since you donated a dollar (seriously, thank you for that). We'll also make note of this. We're currently trying to fix these types of bugs best we can for the full version. So thanks for letting us know!
