I think this game has a really great tileset and pixel style, menu, font, and music. I appreciate that it runs in-browser. Not sure what would cause the black squares everywhere..? Maybe a sprite is missing?
Great game concept with the world-switching mechanic. I think that this blends well with the map design and platforming challenges. The double jump + wall climb movement is satisfying.
Unfortunately, I got pushed and softlocked into a corner by the red eyeball enemy. Not sure where my pink ball friend went, or why I am collecting crystals. I wanted to get to the end, but I stopped after this.
Overall, a cute adventure that I enjoyed. I would love to see it improved and expanded upon.
