About

Cosmic Slice

Read full description

Cosmic Slice is a fast-paced arcade slicing game set in deep space. Two neon blades — one cyan, one magenta — are yours to control. Crystals fall from above, each glowing in one of those two colors. Slice a crystal with the matching blade and your streak climbs. Hit the wrong color and you lose a shield. Let one slip past and another shield is gone. Lose all five and the run ends. The challenge builds level by level — targets rise, crystals spawn faster, and a second crystal type (Swift Crystals) enters the mix at higher levels, moving unpredictably and demanding sharper reflexes. From level 4 onward, bombs appear without warning: slice one and every remaining shield is stripped instantly. Earn Cosmic Dust, spend it wisely. Every slice and every star earns Cosmic Dust — the in-game currency used to buy power-ups and unlock visual themes. Manage your reserves between levels or spend aggressively mid-run; the choice shapes how far you go. Power-ups • TIME-STOP (150 dust) — Freezes all crystals in place for 1.5 seconds. • COSMIC MAGNET (100 dust) — Pulls every crystal toward your blades for 4 seconds. • SHIELD RESTORE (80 dust) — Instantly recovers one lost shield. • AUTO SLICER (1,000 dust) — Deploys an AI robot that automatically slices crystals for 3 seconds. Level map & star ratings Progress is tracked on an infinite level map. Each level awards up to 3 stars based on score. Come back to replay earlier levels for a higher rating or to farm Cosmic Dust before pushing further. Themes Unlock alternate blade and visual themes from the Cosmic Shop using Cosmic Dust — from the default Neon look to Retro Glitch and Supernova styles. No pay-to-win. Ads are optional and rewarded — watch one to earn a random power-up after a tough streak of losses, or pick up 500 Cosmic Dust from the shop. Everything else is earned through play.
