simple and easy to understand gameplay, kinda reminds me one of the microgames in GBA warioware, there is one that you could bounce a mini man up to reach a height to score, also another one to move sth left-and-right to catch the up-and-down bouncing man(not quite remember if they are in a same microgame?) check out warioware if you find interesting, and in terms of the visual, if you'd like to show the yoyo movement on y it might looks better if you could make the background pattern horizontal. but anyway, well done! please keep on!
