It's been a month since I initially released Depth Above, and honestly, it's been an incredibly rewarding experience. The feedback I've gotten has been really useful, and it has helped me push this demo forward, even for this major update. However, I think it's time to move on

This is just a demo after all, and I want to get working on the full game as soon as possible, still, releasing a major update like this has been kinda useful when it comes to stuff like saving and such. If you encounter any bugs, don't hesitate to report them, and I'll fix them as soon as I can. 

Hope to see you in the next devlog ^^
