Space rent prices going up all the time smh... Really fun concept, I loved your use of the sound effects to indicate the values. Hearing a high pitched one got me hyped, and the mechanics for aiming at the cubes was very smooth.
The art is simple and clean, the little house is too cute. I think your idea for the powerups was great, I would have loved to see more of them! Your choice of music was very fitting as well, I enjoyed it accompanying my space quest.
Great work on this, hopefully something gets done about space inflation!
