Pues eso, que intento sacar el logro de matar 20 clonocélulas con la inmunidad activada pero no hay manera a pesar de que creo q lo he logrado varias veces viendo el combo q me sale.

WHY THERE IS NO AUTOFIRE? Its not 1980 anymore. :/ It is essential to any shooter game. Also - its just me or balls bounce too low? Player have very little time to react and with all those tetris blocks flying around game seems kind of unfair.

achievement description, Win a level using only two pills in the Pillman game. How is that actually possible and on which pillman level is it most likely to be attained, thanks.

Some people reported that some generic usb joysticks don't work with the game, and connecting them makes the keyboard not work too. We have been trying to solve the issue but still haven't find a solution. For know, if you have the problem, unplug the joystick and the keyboard should work back again (closing and opening the game might be needed). Our sincere apologies for this problem!...
