While I was playing Bug Heroes, my character moved so slowly that I couldnt defend my food when bugs showed up behind me on a certain round. Sometimes time was just spent moving slowly around without doing much. While the movement controls worked well, there was something wrong with the attack controls. I couldnt kill other insects effectively. Also it seemed hard for me to dodge bullets sometimes. Whats wrong with all these, anyone having met the same problems?
I have an ipod touch 2g, I have faced a lil lag & frame rate drop, but I am Not as much worried as you are, restarted the iPod & it worked smoother. (it took 20 secs for it to shutdown!!! )
I'm a little impatient and just wanna the character can move faster and attack more effectively. I don't wanna shutdown and restart time after time.
When I first started playing the game I had problems controlling Beetle and Spider but not Ant. And then I remembered this is a "dual stick" game, so after making sure I was "aiming" my attack with Beetle and Spider in the correct location (not where I was facing!) then they worked a lot better. Keep in mind that Spider is the fastest, followed by Ant and then Beetle. So - maybe, you were trying to control Beetle, was assuming that he should be attacking where he is facing, and wondering why he moves so slowly...
Sometimes it lags a little bit, but it still dosen't influence the charm of the game. Forsaken Media did a fine job of blending genres well, and the game contains survival, castle defense, and RPG characteristics with a lot of content. Every play-through is endless and goes on until you die or run out of food. It's a fun game.
