I finished the game. It's good but to get 4.5 stars you'd have to: add more interesting or cute dialog, maybe a backstory. Maybe some more decoration, small details, blodstains on spikes etc. Expand the game if you plan on working on this in the future, and make the levels slightly easier and harder neAR the end of the game (like you did here, but with more levels) I understand it's probablu not still in development but if you ever decide to shoot for the moon and build a station, those are just some tips.
