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.

Verdict
The clearest difference is ads: Kosmo Spin at none against Notebook Artillery's shown. Kosmo Spin also leads on rating (4.8 vs 4.5). Notebook Artillery's advantage is update cadence (every 2 weeks vs every 4 months) and ratings volume (148 vs 12). On review sentiment, in-app purchases, device support and iOS requirement there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Kosmo Spin costs $2.99 and Notebook Artillery $0.99 up front. Neither carries in-app purchases, so what you see is what you pay.
Kosmo Spin holds the better App Store score, 4.8 against 4.5. That said, the two scores are not equally well evidenced: Notebook Artillery has 148 ratings behind it against 12, so its average is the more settled of the two. Written reviews complicate that: 79% of Kosmo Spin's written reviews are positive against 82% of Notebook Artillery's, so the app with the better star average is not the one people write more warmly about.
Kosmo Spin ships an update every 4 months, Notebook Artillery every 2 weeks. The most recent releases landed on October 14, 2026 and October 13, 2026 respectively.
