Just beat the game with all the upgrades and stuff, really nice.
Even though I gotta admit that at the end, where only the endboss was left and still armaggedon and other expensive stuff to buy, isntead of grinding over and over, I just cheated myself a bunch of money into the game :-)
didnt change gameplay or anything, just kept me from having to kill same enemies over and over again.
would have defeated the endboss without issue even without armaggedon.
I mean, I took like 1 point damage, while having 12 or something health.
was a really nice game, even though too easy in certain parts :-)
but I loved it, this is the kind of metroidvania I just love to play :-)
