Fun game!
It take a while for me to understand the mechanics. They are deep and well desinged and that's a think I liked a lot! I think they only miss some visual ui. For example, it would be nice to have an off screen enemy indicator (or a minimap that shows them). The fact that you should preserve corrupted antivirus is very clever, but I'd like to know if one is under attack.
Sound and art are nicely done, it's all very consistent withe the theme.
Overall it's a good game, deserve good ratings!
