Krashen
About Krashen
In Krashen you tap the screen to drop moving blocks onto a growing tower. Each block slides back and forth across the top of your stack, and you must stop it at exactly the right moment so it lines up perfectly with the layer below. Any part that hangs over the edge gets chopped off, making your next block smaller and harder to place. The goal is to stack as high as possible without losing all your width.
The game speeds up as your tower climbs, turning every tap into a test of nerve and precision. One mistimed click can cost you precious space, and a few bad moves in a row will end your run. Krashen on Poki Games rewards patience and sharp reflexes equally – wait too long and you'll panic, tap too soon and you'll lose your foundation. See how many floors you can build before the pressure gets to you.
