Development & design of multiple small and video games to create a small portfolio and have fun doing so in the process. I've had to learn a lot of important skills from design techniques to programming languages and hardware architectures. I've been really enjoying making things from scratch, building the engine as i work on the game, diving into the lower level stuff and streaming some of my work!I also participated in a lot of game jams when possible since i find it a great way to hone ones game design skills and meet interesting people to work with.Most of my work in games is visible on my itch profile: https://colinbellino.itch.io
