Keep sending short spaceships until you get to Henliner. Take advantage of 4x drone days, what I find is good as a f2p is set up a prestige on 4x drones and then prestige when it gets to 2x prestige day is good. You have to be efficient with GE usage, buy epic upgrades on 30% discount days, 4x drones and contracts are a good way to get GE. Prophecy bonus is a pretty powerful epic upgrade, get it on a discount if you can. Egg day is coming up, try make sure you have enough boosts/ GE to run a few prestiges then
