Level 28 has an unintended solution where you can finish as a piece with 18 tiles. Really liked the game, and I hope it gets a full release one day.

That was a delightful puzzle game, dear Dan! You already know how much I appreciated it, because I know that you read our article about it and watched the gameplay video, but let me tell you once again that it's great to see that you didn't just managed to implement some solid, good puzzle design in "Theseus", but also implemented a kind of melancholic and beautiful atmosphere in there! It's a sweet game which isn't just a pleasure for the brain, but also for the heart, because it reminds of a search for oneself. <3 I'm glad to see that you still work on the expanded version of it and you got the 4th place in the whole Ludum Dare 35 in it - it's well deserved. I hope you saw that we included your game also in our GOTY 2016 list, too; that's how much I liked your work. :) Keep it up, buddy!

Best wishes,

I just discovered this game recently and it is a superb game, even the demo is already a master piece. Is there hope for the "full" expansion or is the game on hold?

Thanks so much! The expanded version is still coming, but it's going to take some time.

Ace puzzle platformer, looking forward to an expansion!
