Blocky Fish

Blocky Fish is one of those games that looks simple until you're sweating over a single pixel. You control this square fish with a blocky face, swimming through an ocean that gets more chaotic the deeper you go. The core loop is straightforward: tap or click to make a block appear right in front of your fish, which pushes you upward. Let go, and you sink. That's your movement -- no flappy wings, no steering, just placing blocks to avoid obstacles and collect coins. Your brain quickly learns to time these block placements, because the gaps between spiky kelp or jellyfish clouds get narrower fast.

Early levels like "Coral Cove" ease you in with wide spaces and slow currents. You're mostly grabbing shiny coins and the occasional treasure chest that pops out a speed boost or a temporary shield. The satisfying moment here is chaining coin collections without touching the red sea urchins -- they cost you a life instantly. After a few rounds, the game introduces "Depth Dives" where the screen scrolls faster and obstacles like "Razor Reef" and "Manta Mines" appear. These aren't just walls; some move, some pulse, and the minefields require you to place blocks at odd angles to slide past.

Around level 10, you unlock the upgrade shop. Coins buy you a faster block respawn rate, a bigger fish hitbox, or a magnet that attracts coins within a short radius. I found the magnet worthless, but the respawn upgrade is mandatory for later zones. The "Abyss Trench" is where the game gets mean -- obstacles spawn in patterns that loop back, and you have to memorize their rhythms. There's a section with "Pufferfish Gates" that inflate and deflate, demanding you either rush through or wait, but waiting often kills you because the current pushes you into spikes above.

Enemy types include the standard spiky fish that patrol horizontally, and later "Shadow Eels" that dash upward when you get close. No boss fights, which is fine because the challenge comes from the escalating speed and tighter corridors. The most satisfying thing is pulling off a long chain of block placements in the "Neon Depths" zone, where everything glows and the music syncs with the obstacle patterns. Dying resets your score to zero, but you keep your upgrades -- so there's a weirdly addictive loop of getting a little further each time. The block placement mechanic never stops feeling tactile, like you're building a staircase out of thin air while dodging death. There's no real ending, just a leaderboard that shows how deep you got. The game doesn't explain half of this; you learn by dying a lot.
