Hey, thanks for the feedback !
I'll see about the game not quitting in the browser. It's a common problem I think but at least it's quitting properly in Chrome for me.
I get your point about the game feeling too slow at time. I was going for a chill / contemplative atmosphere but I guess I could speed things up a bit.
About seing farther, the fullscale map (you can click on the minimap) was meant as a way for players to plan their route beyond what they could see. But letting the player explore the level freely before the launch is definitely an interesting idea :)
For the cargo, I understant it might not be obvious, it's making your ship heavier / lighter. I'm thinking the game needs a tutorial and at least one situation where they have to adjust it to succeed. Like being near a blackhole and needing to reach escape velocity by setting the cargo very low...
Thanks for playing !
