Thank you! Your feedback was very neat! haha good to know about the bug, it seems that it's happening to more people than I imagined, I sure got the motivation and will make it better. And thanks for suggestion about more things on background and more enemies, the plan was to include at least one boss in the jam build, and I modeled it and prototyped it's gameplay, but still had to do too much to be a really cool boss, so I've left out of the jam build. I do have the motivation, specially after seeing some great advices from other devs. Thanks for the help.
I did checked out 'Europa' and I was very impressed!!! I'll play it soon enough to give you my feedback, but I must say it looks like you have a jam winner in your hands :D
