As for the physics feeling off, the only thing I think feels off is the fact that sometimes you don't collect the coins because the ball goes too fast. And then you try to get them again and you don't get them again because the ball goes too fast.
Whatever the unit AI is for attacking/healing is, it shouldn't over-ride direct commands. Like for instance: Viegraf (AKA the starter hero) Would die because my pixies (AKA healers that DON'T FREAKING LISTEN) wouldn't move where I told them to because units immediately around them were slightly damaged. Any commands given by the player should over-ride the unit's AI. Like, I'm not rating this until I know whether or not you're ever going to fix that.
I won't judge this game based solely on the fact that it seems like it's taking forever to load on even a high-end computer... but seriously, you NEED a loading -bar-...
Nice little toy. But since you obviously can't capitalize all the words in the name like a good person would with a game he values, I'm believing the people saying "stolen".
This game could use upgrades, perhaps pause and spend your score on upgrades, some keyboard shortcuts like enter to play again, and perhaps a bit more focus on the physics engine if you really want to call it a physics game... I see where you say that, though, due to the viscosity of the blob you play. All in all, a game that could be improved. A good game, that can become a great game. 4/5.
I want to thank the person who did the music. Mostly because I love this game's originality, yet even more so, I love the music. Mostly because I have a slight fetish for strange time signatures, and parts of the song sound like the 5/4 time signature you find in the "Mission Impossible" theme. Of course, it being the "Mission Impossible" theme that it seems to be akin to makes it even more enjoyable.
Ah, a simple puzzle made by Einstein himself. Challenging, as it causes the one trying to solve it to think in a more lateral sense. Yet, simple if you know the kind of puzzle.
