well, though it does seem to be a LOT like Age of War I do have suggestions. First off, make the upgrade page easier to understand. second, how do you punch I'm pressing space, but nothing happens.
grrrrrr..... I beat this months ago, with a fully upgraded ship and tons of money, and the thanks I get is my save files being deleted, rude! This will not affect my rating, luckily for you, which will remain at 5 stars.
sorry to keep posting, but I have to comment how people are saying the screen is too crowded, well, duh it's supposed to be difficult. I think the best weapon in the game comes 80-85 power. It is a force field shot that I think goes through enemies. my ending was 85 power, 35 engine, and 90 shield. A nice balnce between a fast paced game, a strategy game, and a shooter. (strategy because you need to order your power- ups in a good way.
