15 Coins is a deceptively difficult minimalistic arcade game with one goal: collect 15 Coins before you are killed by your clones. Your ship is always moving forward and all you have to do is tilt or tap to turn left and right to collect 15 Coins. The only thing standing between you and victory are endless clones that follow the path you've traveled. Crash into a clone and it’s game over. You’re not alone though, you can collect a power-up to temporarily freeze the clones and smash into them to destroy them! Can you avoid your clones long enough to collect 15 Coins? ================ "15 Coins is a rather intriguing game that I have fun playing, and a fantastic example of how minimalistic, challenging arcade games should be done." - 148apps.com - Rated 4.0/5.0 "15 Coins is a simple arcade style game that is impossibly difficult. Similar to Flappy Bird, it makes you want to keep playing over and over, no matter how poorly you perform, just to try to get one more coin before you die…" - iDownloadBlog.com - No Rating "15 Coins is hard. Alright, that was the shortest review I've ever written. I'll be back Monday." - Cult of Mac - 4.0/5.0 "If you're a fan of these minimalistic arcade games that are all about skills and reflexes, then you should pick this one up." - App Advice - Rated 4.5/5.0 "Worth Way More Than 15 Of Your Coins" - Apple'N'Apps - Rated 4.0/5.0 "Extremely simple. Extremely hard. Extremely addictive" - Appgefahren.de - No Rating "15 Coins has me locked in a cycle of trying to outdo myself. It's a stylish and accessible game that's worth a look for anybody who enjoys quickfire action and high score-chasing." - PocketGamer - No Rating

Apple called it "sketchy — in a good way." Multiple-time Game of the Day in 80+ countries. Nintendo Force gave it 8.5/10. And it started as a doodle. Once upon a time in a middle school computer lab, a student ignored every assignment for an entire semester to fire cannons at a friend. That student grew up, spent 20 years making games professionally, and eventually decided the world needed a proper love letter to that wasted time. This is it. Notebook Artillery is a hand-drawn artillery game inspired by the classic Mac game that got confiscated off school computers everywhere. Set your angle. Load your powder. Fire. Account for the wind. Try not to hit your own tower. Play your way: Solo target practice — break floating targets across randomly generated stages VS CPU — take on a computer opponent Local multiplayer — challenge someone in the same room What makes it feel different: Every frame hand-drawn in Procreate — ruled lines, coil binding, pencil textures, the whole notebook aesthetic Trees splinter. Towers explode. Cannonballs collide mid-air. Wind changes everything. Read the flag. Use your shot trails. Unlock stickers by pulling off feats — first-shot eliminations, mid-air collisions, and yes, accidentally destroying your own tower Randomly generated stages mean no two games play the same Made by one person, with audio by Kevin Samuels and Switch/console ports by PolyCrunch Games. No AI tools were used in making this game. All art hand-drawn. Developed in GameMaker Studio.
