I've put a new build up (2010033001) with a couple of bugs fixed (hopefully!), added a skill-level (which controls the speeds of the enemies), and reduced the code a little (~400 bytes) in order to try and get my dream eight levels in. People have been asking about the cheat-codes - they're eight ch...

Maybe I'm just stupid, but how does the cheat code work and what does it do? Allows you to type in an eight character cheat code. Try "DELTA " (note the three trailing spaces) to start the game at the fourth level. If the code is not valid it will immediately disappear from the screen. If it is val...

WIP build updated - 2010032801 - same link as before.

Build has the pause key, cheat-code system, various code optimisations, and 2 new levels.

All feedback greatly received.

Thanks Bobs, that was the kind of thing I am after. I can see how using a back buffer would work. All that would be left is a check when the player gets close to an edge. Cheers Back-buffers are very handy, but take extra time & memory, so you need to decide on a case-by-case basis whether it is wo...

The usual way is to store the map as a list of tiles and the draw routine finds the tile at the top-left of the display and then draws each tile required to fill the playing area. VIRUS does this, but backwards, in that it actually starts drawing from the bottom-right, and works left then up to the ...

I didn't realised I had a tester! I though you guys were just playing it for fun?

Guilty as charged - a big influence.

My current build now has the pause key (for Shaun), and the cheat-codes for infinite health/ammo/keys (for Moggy). I had a play with re-doing the compressed format, but nothing has quite come close to running the whole map through a good compressor, so I'm sticking with that. Should be able to get 8...

New build! Same link as before - http://www.bobs-stuff.co.uk/extras/virus_wip.zip (will always be this link until release) - with the following updates: * Once the virus has been purged you must now head for the exit. * Three levels are now in the game. * Collectable objects flash to make them stand...

Maybe something a little more unexpected suddenly appearing.

Just my 2 cents worth.

Yup, that's on the to-do list - something a bit faster that moves diagonally is one idea.
