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.

About

Bit Invaders

Read full description

Bit Invaders is a classic game reinvented for binary number. Every spawning cat has a decimal number, the way to defeat them is to enter the binary number of their counterpart. The game has 10 levels to begin with, plus a endless challenge mode after clearing all levels. There are also bonus scores for speeding up and hiding the binary hints. In endless mode, difficulty will also raise as the game progress. MEOW!
