I think it’s enough for now. This game has reached an stable state, and from now it will be discontinued (except if somebody founds an important bug).
What’s new in V1.5:

• A.I. improved, specially on edges and reaction time

• Some improvements on images of Main and Options screens

• Player sprites now are correctly displayed when you go through a platform from under. And player firing sprite now is correctly centered.

Any comments are welcome. Please check the game and enjoy it as much as I have enjoyed creating it :)
