かわちいぶつかりおじさん

"Kawaii Ibotsukaori Ojisan" is a 3D action game where size is justice. You control a slightly round and cute old man. Walk around the city among colorful people, find opponents smaller than yourself, and charge into them! Each time you collide, the old man grows bigger and bigger. Conversely, if you bump into someone larger than you, you'll be knocked back and shrink, so be careful.

Don't hesitate against larger opponents—fire the "Ojisan Beam"! When the beam hits, the opponent shrinks more and more, and once they become smaller than you, there's nothing to fear. However, if you hit them with 3 consecutive shots, the opponent will flinch for 1 second, but then enters an invincible state for the next 1 second. During invincibility, attacks have no effect no matter how much you hit them, so the key is to time your attacks carefully. Furthermore, larger opponents slowly approach you, and smaller opponents flee when hit by the beam—the city's residents have proper "personalities."

Move with W, A, S, D or arrow keys, fire the beam with the spacebar or click, and rotate the camera by dragging. If you reach twice your initial size, you win; conversely, if you become the smallest, you lose. Despite its squishy and pop appearance, if you let your guard down, you can be shrunk in an instant—enjoy this surprisingly serious survival-of-the-fittest battle.
