Addictive and fun
This is one of the most fun and gripping games I've played on NG in a long while. I can see you've put alot of effort into it and it really did come out good.
The whole system layout of the game is amazing, lots of brilliant modes and great instructions nothing wrong there. Intro was a little long but everything else was perfect, a standard for other games of this type.
The graphics of the game were quite simple but didn't need to be that complicated anyway. The animations on the Blobs were very good, and the player was nice animated aswell.
I really liked your choice of music, nice and atmospheric, really set the mood for each stage. The sound affects were also well chosen and well timed.
The game play was nice clean and simple. The amount you had to kill was near impossible to reach and it did get kind of repetitive, maybe if you put some medal and/or goals you could reach it would make it more fun and riveting. But other than that very nice, and challenging at some type of blobs.
Overall a very good game, I would recommend slightly tweaking some aspects of your game, as said above, if you plan on making a sequel. Other than that, amazing. Keep up the good work
