Build 0.1.5.4 and Plans for the Next Few Updates — Space Travel Idle Steam update #381342

Build 0.1.5.4 Hi guys, here's a small patch I send out before I start updating some gameplays and implementing a tutorial! Before I finish the above, I'll slow down the update frequency. But it won't take long (probably one week)! Feature Updates: - Added tooltips in Battle Panel Content Updates: - Added a Energy Source on Venus consuming Biomass - Set Mercury as the end of the journey for the current version.
