For those that say lvl4 is impossible: it can be done really easy with a good strategy. I have a good score did not cheat at all. (but finishing it in under 4 minutes seems impossible...so there are changes some did cheat)
About the mouse laging is because the ship moves at a certain speed. It goes to the position of the cursor at it's speed, not at the speed of your mouse. As for the enemy's blinking, that is a good idea.
You can't win if the computer moves left-right at the same speed as the ball. The graphics are bad and those square that want to be effects should really be removed.
You can just hold the mouse button and it will fire. You don't have to click for every bullet. As for the three rows, it's because you are in a tunnel inside the mothership.
Thank you for your comments. Don't forget to make your own levels, send them to your friends and also to me and maybe I will include them in a "user created levels" version of the game.
For anyone that says it is a trial version: The game can be played for free on flash-play.net or toolight.com and also it can be downloaded as an AIR application free of charge.
About the bug when you or your apponent start using different cards. I will try to fix it. Until than, when this happened, just refresh the page and continue from where you left. Your progress is saved.
Louskan, you can remove the card if you don't have mana or just don't want to use one in that turn by clicking on "Discard". Also, it is not based only on luck. Like all card games, it has luck involved, but it also does involve knowing what cards to use...it is a combination of both. Glad you like it and thanks for your comment.
OK! I fixxed lvl 11
And this is not a rip-off...just because the game is played in a spreadsheet. I have my own power-ups, my own way of stopping the brick and many different things.
If you all think this is a rip than I will remove the game. Sorry for this.
