That was quite an enjoyable game! The art was nice.The game was fastly paced, which really added to the fun! And the difficulty of the viruses were well-balanced, too!
But yeah, as said below, I wish there was some sort of auto collection for the anti bodies. In more frantic moments, I usually forget that you actually need to collect the anti bodies yourself, resulting to myself spending 5 seconds waiting for nothing lol! But idk that might take away from the challenge.
