Acid Assault. Last updated, late 2006. Will I ever work on it further? Perhaps. For now:
Some notes
You control the cannon with the left and right arrow keys.
From the sky come chemicals, threatening the balanced pH of precious lake. The green ones are acids; the purple ones, bases.
The aim of the game is to neutralise the falling chemicals. To neutralise an acid, press ‘Z’ to fire a base. To neutralise a base, press ‘A’ to fire an acid.
Sometimes the chemicals will fall in sets of more than one. You can neutralise these by firing out your own composite super-chemicals. To fire multiple bases (for neutralising acids), use the X (2x), C (3x), and V (4x) keys. To fire multiple acids (for neutralising bases), use the S (2x), D (3x), and F (4x) keys.
You can also neutralise these super-chemicals by shooting multiple single shots at it. If I do ever work more on Acid Assault, I will remove this option.
Occasionally some salt will come falling down. You can pick it up with your cannon (by moving into place so it hits you) to gain levels. These don’t really do anything in the current version.
As mentioned, the levelling and scoring system isn’t particularly good. It will be improved maybe.
Very definite.
I think an option to end the game and close the window would be an excellent addition.
Press escape.
