For not being into MLP, or even really gambling games, I honestly enjoy this premise. I do have a couple of critiques.
1. I'm currently running the game on lowest settings on mid level PC, and it sounds like my fan is going to explode. Not only that but the game seems insanely slow. The Luna mini-game especially chugs along at about 1 inch every 5 secs, and even walking around takes way longer than it should. In contrast, the poker minigame seems to run a lot faster than it was on the last build, so definately do more of that! So more optimizations, or options to decrease quality or something would be nice.
2. Third person camera is terrible. I don't know if I'm missing a control, but it straight up doesn't follow you. It also has a tendency to zoom farther and farther out, until it starts clipping through stuff. Thank God for the loading screen that tell you that the C key goes to first person. Every time I load up the game, the default is third person and I always forget how to fix it for a couple minutes.
3. I think someone else said it, but the tank controls are a bit wonky. If the 3rd person camera was better I wouldn't mind, but because I pretty much have to go third person, the holding down the mouse to look around can be a bit tedious.
I still look forward to seeing where this project goes, and I hope you can continue to improve and refine your project!
