IDEA
You control a space ship and fire shots to destroy the mothership at the horizon. Use O and P to control the ship, autofire is enabled
The scroll effect is created changing only the attributes with the LPRINT Hack! (redirecting LPRINT TO attrib RAM from https://blog.jafma.net/2020/08/29/efficient-basic-coding-for-the-zx-spectrum-v/#en_5)
We create UDG as columns of 8 attribs rows to be lprinted
We put all the udg (to be used as attrib data) in a string that is scrolled

Love this game! The colours are so vibrant. It has the vibe of SEGA Space Tactics or Space Harrier.
