Toss your yoyo and build rainbows to jump on! 13 different cute enemies stand between you and your triumph over the eight towers!
BTW I didn't include some of the nuances of yoyo control in the instructions in-game, but once it's coming back to you you can hold the x button again to cause it to move on the y, rather than x, axis. You can build stairs this way, or a shield from projectiles.
You get different items at the exit door depending on how thorough you were, so be sure to revisit the levels and try to beat your previous score!
A labor of love that has just sort of poured out of me over the last few weeks, I'm excited for you to try it. And if you experience any runtime errors or memory running out, please let me know. To the best of my knowledge I fixed those issues, but you never know.
