About this game
Many years ago, psychologists discovered where “life” comes from.
They claimed that in every mind, in every soul, there was a world formed by creativity.
This world, powered by imagination, created life. Without it, personality wouldn’t exist.
They also discovered that under certain conditions, this world can collapse.
Explore a collapsing world full of new friends, old enemies, and a dark secret that could be the key to saving the world?
Features
6 (six) large areas full of amazing sprite work and music!
A story full of humour, horror, friendship, and maybe even... love?
A bullet-hell battle system inspired by games like DELTARUNE, OMORI, and Touhou!
A really cool character named Vex who likes clams.
A large and beautiful soundtrack by a pretty cool person!
And at least 1 (one) other cool thing!!!!
