Although making two games instead of one wasn't ideal, it was a lot of fun to see how quickly I could create two small prototypes and made for a great challenge.

It's nice to hang out with other game makers while you're all frantically coding and making content as fast as you can!

GM48 is not just a jam it is a fun way to test our knowledge.It makes us think in different ways to come up with good ideas.I think everyone should try it.While I was creating Static I learned a lot about pixel art and my weaknesses in game development.I really enjoyed it.

The Jam was a lot of fun! One tip I can give to future participants: Nail down what you want to do as quickly as possible! If you don't, it might come around later and bring unwanted trouble!

No other game jam offers an opportunity to test your skills and learn with a variety of unique themes as much as the GM(48) does. I'd highly recommend it to everyone, from beginners to professionals.
