I've tried to push renpy to its limits...
Game has a few cool details such as

• Unique battle systems
• Weather conditions with serious effects
• Cards that can leave your deck and face you as bosses
• Difficulty levels that truly challenge the player
• Animations, shaders, and small details on every screen
