Thanks! It's a playable version of one of my video series, kinda made it as an attempt to see how much effort it would be.
It's unlikely to advance much beyond this (due to low viewership on the video series); however I might make a couple of more improvements to improve replayability (better menu screens with restart/end, preset difficulty levels, upgradeable planets, etc), and I have a half baked android build that I'd like to polish a bit and upload to play store.
