Challenge Go (aka Challengo / Ray's Challenge) is an action/puzzle game set in an expansive world, inspired by classic block-pushing games like Chip's Challenge and Sokoban. Originally released in 2006, it was quickly featured on the YoYoGames Sandbox where it went on to receive over 30,000 unique downloads. It has since gone through numerous major developments. The latest revamp adds touchscreen controls and sees its expansion to additional platforms. An online high-score system per level allows you to compete against others for the best time. Secrets galore including cheat codes and hidden areas. The goal in Challenge Go is simple: fight your way through each level to the portal to reach the next area. Get lost in forests, swamps, deserts. Walk over the sky in ever-changing weather and light, and even navigate the depths of space. Sneak through cursed ruins, war zones, dark labyrinths and haunted houses. Use items to run faster, open doors, pass hazards, and destroy. 100 levels total to challenge even the most dexterous.

A retro '90s-style vertical bullet-hell shooter you can play with one finger — free, and fully playable offline. Weave through walls of bullets across 3 stages and massive boss battles. Skim past enemy fire to "graze" for score and bomb gauge, and turn the tables with screen-clearing bombs. Clear everything, and a hidden true battle awaits. ◆ Features - Intuitive controls: drag to move, auto-fire, double-tap to bomb — one-handed play - Graze system: near-misses are the path to high scores - 3 stages + more: unique midbosses, bosses, and a hidden final boss - Achievements & rankings: 14 achievements and global rankings (with per-language boards) - Difficulty options: EASY / NORMAL / HARD - 17 languages supported, works offline ◆ How to Play 1. Drag to move (your ship fires automatically) 2. Double-tap to trigger a bomb (clears enemy bullets) 3. Graze enemy bullets for bonus score 4. Watch a short video to revive after game over and push on for the clear Note: This game contains flashing lights. Player discretion is advised for those with photosensitivity. ◆ Made for players who enjoy - A retro arcade shooter, pixel art, neon lights, and a tense trip through space - A quick game during a break, or a longer high-score and score-attack session at home - Learning to dodge patterns with one hand in portrait mode instead of aiming every shot - Starting on EASY, settling into NORMAL, then taking on the hardcore density of HARD ◆ A score run with choices NOVA STRIKER is a danmaku-style shmup where reading a pattern matters as much as reflexes. Your ship fires on its own, leaving you free to steer through the gaps. A close dodge earns graze and fills the bomb gauge, so a daring line can be worth more than a safe one. Spend a bomb to clear a crowded screen, or save it for a boss phase: each run is a chance to refine that decision. ◆ Reasons to return The three stages are built around distinct enemy waves, midbosses, and boss battles, culminating in the hidden final boss. Choose the pace that suits you: EASY introduces the flow, NORMAL rewards consistency, and HARD asks for careful routing through thicker bullet patterns. Chase all 14 achievements, improve your high-score, and compare results on global leaderboards with separate boards by language. ◆ Play on your terms This is a free single-player action game for portrait smartphones, designed for a few spare minutes or repeated practice. It works offline, so a connection is not required to fly and dodge. A rewarded video is offered only when you choose to revive after game over; there are no forced ads interrupting play. With drag movement, auto-fire, and a double-tap bomb, it stays focused on the arcade rhythm. Price: Free to play, with one optional one-time purchase (rewarded ads only — no forced ads) Supports: Smartphones (portrait)
