Neat game, loved going through all the different technology-decorated scenes in this!! The GB world was especially fun to explore with all its secret ladders and pathways to discover, and I especially can't wait til that one reaches its final stage in development :D
I did encounter a fatal error while entering the leftmost nexus world that said it couldn't load "img/doodads/bunny.png", and didn't let me access that world at all unfortunately.
Another thing I noticed was the major speed different while sprinting, the 4x normal speed is great for playtesting but is a little fast-paced for a YNFG, and I had to slow down just to interact with some things ^^;;;; maybe changing it to 2x normal speed or adding an extra toggle would be nice to have to not explore the world too quickly, yknow?
Love the style and how cute this is, hope you decide to touch this again one day! ^^
