Really had my interest at first. I happen to like Big Fish, Little Fish games and I'm happy to see new takes on it. However, it reached a point where the game simply began to drag on and on as I played. There is a point where the human eye is unable to judge and compare details accurately and there are points where I can assure myself that my judgement was spot on yet was punished for it. Therein, one must avoid chance and chase after only 'safe' targets which, at later points, lack greatly in appearance. One hit, even with full resilience, is a setback of a couple of minutes of more dodging around a screen (one that uses mouse pointer distance as indicator of acceleration provided) where quick jumps have the pointer leave the play area constantly.
I like the effort and idea and I think that it can be much much better with some sanding of rough edges. I'm confused if the game is supposed to be action-paced with a focus on snap accuracy, as the appropriate badge indicates, or a test of patience and endurance as the game play itself indicates. It cannot be both. While viral diseases can last weeks, months, or years I do not feel that a game depicting such an internal battle should relate to that level of biological accuracy. Ha ha.
I dealt with some mild processing lag on my system which is probably no fault of the game itself that was only really noticed during 'Lymph Baths'. I also clipped red cells larger than myself by quite some distances in making quick dashes through gaps that failed to 'hit' and set me back even further. This was a good thing for me but may or may not be intended.
Also, the mouse pointer is moved -by- the player to move the player's game avatar, sometimes called a character when sentience is related or assumed, which can simply be called The Virus in this context. The mouse pointer does not move the player itself. Argued semantics, perhaps, but just a side note of personal preference.
Thanks for the game, though. My apologies for not completing it to give a full assessment. I only made it to Smallpox and found myself inevitably wandering around for about 6 minutes playing keep-away with no progress before I lost interest. Don't let my experience deter others from trying, though. Every gamer has off days; today could be one of them for me.
