Monster Mutation Machine is basically about mixing mutagens to create funny looking monsters (mutagens is the yellow, green and orange liquids falling out of the spouts) The scoring system work is basically a count down every monster starts at 10,000 points and depending on how much time you left pass and how much mutagen is collected for each part, your score will be higher, so if you want a higher score, either click a lot or play  a little longer cause these monsters need time to brew.

It can be played for free here:
