lol ya....I just went money. I put all my points into investment until I got 50% interest then got anti matter shield and the 25% defense upgrades, well except for the bullet one. Basically only spent money when i needed to, buying sticky immediately since it helps so much early level, then the shield since regening and refilling life is amazing, and healing to keep my self alive. Also right before the 10th level bought the dmg upgrades needed to kill the enemies with their own shot in one hit and speed upgrade one level below that, but just that much. Ended up with a few billion at the end. XD
BTW, make sure to kill rockets fast on early levels, they are a B and will get you killed often with this method if you don't watch out.
Ya, pretty easy to get the hard badge once you have enough money for everything. BTW, it's best launch at a low angle and use a freaky at the beginning so that you have a fast speed forward plus the upward distance boost from the freaky. After that spam thrust followed by skis as per diode's suggestion. Best score: 8867m
Really easy game, just fill your deck with crystal conjure and curse (bout 6 of each), like 4 of each of the requiters and a good amount of the high cost cards to make use of the massive resource generation. No crappy cards either. =p
I'm sorry but I really wonder if there was any play testing done with any of the later challenges because it seems that around half the time no matter what I do on my first turn I die as soon as the opponent goes. It really comes down to if I'm lucky enough for the opponent to just play crap the doesn't do anything if I'm to beat a challenge. The game has a nice concept but with this complete lack of strategy it just makes the game suffer horribly.
