A lovely logical puzzle game about the many-worlds interpretation and quantum mechanics.

<ul class="bb_ul"><li>Theta is a little girl who turns left every time she hits a wall. She is curious about the sinking world and discovers a mysterious place, where she picked up a fork that can split her into multiple copies of herself, and from that moment, the world changes forever.</li></ul><video class="bb_img" autoplay muted loop playsinline poster="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/3219580/extras/cef654da6c37e3b391e022a5651b1615.poster.avif?t=1769777228" width=1170 height=652 ><source src="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/3219580/extras/cef654da6c37e3b391e022a5651b1615.webm?t=1769777228" type="video/webm; codecs=vp9"><source src="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/3219580/extras/cef654da6c37e3b391e022a5651b1615.mp4?t=1769777228" type="video/mp4"></video><ul class="bb_ul"><li>Use the power of splitting to solve puzzles!
