Loved the game. After 100% in game completion and getting all achievements I would definitely recommend. If you like metroidvanias you'll love this. Hope there will be some DLC or maybe a sequel in the future. **NOTE**

Ever watched Osmosis Jones? Well, it's like that except you play as an armless pig virus and you're inside a dog. Key Points: * Keyboard is recommended since you free aim with your mouse. Hover on holding W key is kind
