I really enjoyed moving my black hole around, and the joystick controls made it work really well on mobile! It would’ve been nice if I could have scrolled the upgrades lists by dragging, but that’s a nitpick.
Since the core mechanic was so fun, I would’ve liked to see more don’t with it. For example, further increasing the collection area or making the black hole move faster. Perhaps a mechanic making some stars spawn 1 tier higher, etc.
Great game, and good potential for expansion!
