✦ AI summary
Players praise the game's original concept combining Sudoku with horror elements, noting the atmospheric tension, engaging gameplay that rewards strategic thinking, and fun cooperative potential. However, some find the premise divisive—particularly those who dislike Sudoku—and the AI enemy can feel inconsistent or overly punishing once detected, though most still appreciate the creative execution and immersive dread the game creates.
Very interesting and I love the spirtual vibes it gives off, my son really enjoys the sudokus while I fend off the bad guys. Which makes it even more fun and WAY more interesting. Thank you, for creating this masterpeice. Highly Recommended7 found this helpful
I hated sudoko, before i played this. Now this game gives me a reason to hate sudoko. 10/106 found this helpful
An interesting premise executed pretty well! If you know how to play Sudoku, the classic number puzzle game, but felt like it needed more dread, then this is the game for you! We had a great time with friends navigating the terrors and obstacles to filling out the numbers whilst being pursued by the enemy roaming the level. Fun with friends that can help fill out puzzle while the player keeps track of saving and putting in the correct numbers. PROS: *Awesome idea that I would've never thought of *Multiple levels with new gameplay challenges integrated in slowly *Atmospheric sound and visuals that keep you tense CONS: *Monster can be a bit unforgiving once you're spotted Oh! And here's video of our Gameplay & Impressions! - https://www.youtube.com/watch?v=U48GMCc0jQQ5 found this helpful
Honestly i almost shat my pants. the game's graphics and atmosphere are actually super captivating, and the way you are forced to strategize and plan your "path" is super engaging. you have the freedom to win in a number of ways, and none of them save you the terrifying, soul-ripping DEMENTOR'S KISS you feel when that ♥♥♥♥-ass hunk of metal chases you. 10/10, would recommend u play with brown pants on. EDIT: Just played level 4. actual schizophrenia in first person5 found this helpful
