Don't why there even is a shop when you can win the game naked with your starting pistol. Double jump and teleport to dodge. Homing bullets so you don't have to aim.
With key 6 there is a big black robot that you can jump over and get to a door 7. But there is _nowhere_ else to go. I've done two loops now and picked up the extra cat claws, but there is nowhere to go.
This is the greatest educational game ever made. I actually forwarded a link to my Algorithms professor. Turing machines are on the final; this is a great study aid.
Needs to ramp power up quicker on pull. To get full power, you need to go off screen. Or worse yet, you pull back on to a ball choice and it picks the ball as you fire.
Missions get easier as they get near the end. Like Mission 9; once it goes from 13 ninjas to 2 warlocks, you can just keep it on fast forward. And having a single big guy as a leader is pointless. The worst he can do is steal one gem.
If your "Attack" button goes out, don't bother finishing the round. It won't end. Must think there is still a guy left, but it sends future waves fine.
The zooming is awful. My cannons shoot further than the screen so I'm constantly shooting off the radar. The enemy ships are never on screen unless you are touching them. Let me control zoom so I can pull it out and actually play the game instead of practicing your dramatic pow curve zooming.
Puzzle Bobble fail. The powers woud be cool if it didn't have soldiers you cut off just walk back up to join the group. Defeats the whole point of saving a guy and setting up a combo.
Archers being able to shoot in to melee breaks it. Every missile troop is fighting the whole time, and ground have to wait their turn. If you couldn't shoot in to melee, then infantry could run up and stab the archers in the face.
Clunky controls. When you walk up to a pedestal with your hands full and hit space, just have it cycle through the three each time you hit space. Or keys for set-down-left and set-down-right. The clicking on a tiny little icon blows.
