This is a really interesting game. I like it!

Edit: I may have softlocked myself though. gg

This looks great, I am excited to play it. Are you Korean?

Yeah, I’m Korean. And thanks for trying out this demo. I want to make this one a full game someday…


I just finished this demo, and really enjoyed it! Really nice aesthetic, and well designed puzzles - took me a bit to figure out the end! And the gravity symbol reminded me nicely of vvvvvv while giving it your own twist.

Please make more!


Thanks for playing it!    I worked really hard to design these levels.

And yeah, VVVVVV was the main inspiration of the gravity symbol.

I always thought it will work great on puzzle platformers, so I tried it myself, turns out it's way more interesting than I expected.
