Dr. Ultra (+ Snake)

Post by tokra »

Name: Dr. Ultra (+ Snake)
Author: tokra
Released: Jan, 28th, 2017
Requirements: VIC-20 unexpanded, paddles.

Description: You are Dr. Ultra. With your ultrasonic-laser you need to remove kidney-stones, which you can only see for a short moment when firing your laser. My entry for the Global Game Jam 2018. Done in under 48 hours at the University of Bremen Jam Site. Bonus game Snake done in under one hour.

This games uses both paddles. To reduce jitter I wrote a small IRQ-routine that evens out the paddle-jitter first by always reading the paddle-registers always at the same raster-line and then also calculates the new paddle-values as such: new_paddle = (new_paddle + old_paddle) / 2

You need to shoot each stone two times (once which each paddle).
