This isn't a straight particle game...by which i mean, you're in a circle (since it's 2d) that's rotating. So...those who can't stand the physics are saying that no matter the spin you throw a tennis/rubber ball off of a wall with, it should bounce the same way.
Momentum does seem odd, and it's still EXTREMELY frustrating...but is a different (realistic-ish) take on physics.
for example, on the level where u bounce of the ceiling...try running right after you jump...you should angle to the left after impact.
that being said, WAAY too frustrating, imo.
1/5...Puzzle Quest without the interesting storyline, graphics, choice in level-up, or varied opponents & opponent playstyles.
Extremely repetitive, I only kept playing to see if it changed...it never did.
