meh
im really a big fan of the MMM series. but for my taste, you changed too much. why is the slingshot gone? with it, you were able to shot as fast as you wanted any by improving the launcher you were able to shoot faster. and there was the risk the energy ball exploded if you pulled it back too far. i liked that.
i don't like beeing able to move too. maybe on some levels, but its annoying with the kickback throwing you completely off screen.
also, why does the air strike hurt you and the turrets? its far to less powerfull and fast for that kind of sacrafice. and shifting dimension takes so long, after the airstrike you are completely screwed if not all enemies have died. (in portal mode)
beeing able to change youre skill points during the game may be helpful, but it makes the game fairly easy. for instance, if you are invulnerable, you can skill on speed and play cannonball or short befor shooting an special projectile (black, anti matter) upgrade it to the max and then shoot. and so on..
the stop game and then use special weapons is useful too, but again, it makes the game too easy. but there is a little bug, if you want to place one of the special weapons under the weapons window, you place it but immediately select a new weapon (if its usable at that moment) its not so annoying if its a different weapon. you place it and then you cancel it, but if its the same weapon, it means that you have to place it somewhere else, becaus its not possible without reselecting it.
and it really needs a mute button and also quality change button.
there is a little bug too: the white projectile sometimes sticks to an enemy like the golden one.
(im a bit sick of all the old enemies too, but its cool that they can fire now)
