Thanks for playing! It's hard, I've never got past the level 3 wall.

I tried to keep the spawns rare enough that you have to make difficult choices. At the start of every level, you can refill either ammo or fuel. I think you have to get a really bad seed not to get a single extra fuel in the level. I'll take a look at whether it needs an increase. 

Thanks for playing the game! Thanks for letting me know I will take a look at these. I think it may be because is only possible when travelling above base speed. I think you cannot exit the web build of the game that is set to autoplay.  

Thanks for letting me know and playing the game! I just pushed an update that gives invulnerability for the first moments so soft lock is not possible.
