It's a shame that they launched a good game like this with many glitches: 1. movement problems in the scene-phase transitions or when trying to move faster or when using several powers together. 2. the mouse stops to respond when we're shooting or using powers. 3. force field's power with problems with collision. 4. phases with problem with collision, what avoids us to pass to next phase. 5. problems when we are holding in the ledges. 6. unbalanced powers with some enemies: you beat a stronger one with one's power but this power cannot beat a weaker foe.
