Well, this was an interesting one. The difficulty spikes from level to level can be quite the roller coaster. Also, the Generic Iron Maiden Regenerators deal way too much damage compared to the other enemies, 3-4 hits will kill you easily. With a damage rating like that, they should have been a lot slower to compensate, especially since they aren't that rare an enemy.

Thanks for the updates. So, I have another gripe. While I realize this is a free game, so adds are to be expected, having one at every single area change is incredibly annoying. Could you change that to, oh, say every three or four? I can live with adds, but that's almost unbearable. Would yuh mind working with us a bit? Since the last time I played things are definitely better, but THAT is annoying.

This app is so full of ads, you never get to play it! A 2 minute ad before you get to the main menu, then a 1 min ad before you go to the 1st level! No controls for brightness, volume, or skill level. This renders it unplayable! No tutorial is available, and this game needs it! It looks like only 2 levels are free-2-play, all the remaining levels are locked. Don't waste your time downloading this poc!!!
