Day 01 - Brainstorming, Concept Art, Outline

My amazing concept art in Paint. You play as Bear, the Dragonbear in a side scroller where you adventure through floating structures and avoid running into dangerous obstacles.
I'm using Game maker Studio 2. I'm not very fond of having to build renderers or other such things, so I feel content in using ready made game engines.
What language or software are you using?
And thanks tdelarosa :D I still have to implement pretty much everything xD. But hey, I still got about 3 days.
@tdelarosa723 creating 3d assets from scratch for 7 day game jam? Sounds risky.
@HappySlapp I wanted to try GMS, but necessity of internet connection is a big no-no for me. So, I'm going to learn Gideros... sometime. For this project, I use Go with BearLibTerminal.
Btw, Fleeing the fire is open source. Sources will be shipped alongside binary release, but if anyone is interested, it's possible to track development via bitbucket repo, with open issue tracker.
@Vedor. It is very risky indeed. Look out guys I am living dangerously over here haha!
I should be finished modeling/texturing all my environmental assets before the weekend. Just finished coding a prototype for my endless side-scroller. It was easier than expected. Now I can generate random chunks that connect with each other with zero overlap. Sweet!
