Tried to do my best, but PICO-8 is a harsh mistress sometimes - the resource icons are 5x5 pixels total, for example, which makes it hard to make them readable.
Is there any particular part that caused you readability troubles? I can always try to improve stuff, though tooltips might not be the way to go on a cramped screen like that.
I'm gonna try to improve the readability of the resources for the next update. I'll also put a resource chart in the quickstart so that it's clearer what's what and what it does (it might be hard to put one in-game due to PICO-8 space restrictions). The resource collapsed stars make is "energy" - it can a) replace anything a planet needs and b) increase any planet's production
