Name of Software:
Catcher

Author:
Donkeysoft

Release Date:
2017-12-29

Requirements:
Unexpanded ZX81

Description:
Written in powerful Sinclair BASIC; a ball drops in the play area, you must catch it by identifying the column that the ball is falling in by pressing keys 0 through to 9 inclusive. The higher the ball when correctly identifying the column, the more points you'll score. You have 9 lives in total.

"CATCHERLR.P" is a new version; use keys 5 and 8 to move your catcher left an right. Score ten points each catch. If you do well, the ball will fall from a slightly lower height, making it more difficult to get to (skill level increases at 90, 180 and 270 points).
