i agree with Ouanonfor completely. reward system is too unbalanced. if your ship gets too low on health, you can't save it. i had repairs upgraded about twice per category, main gun upgraded a few times, two drone ships, and two laser cannons. i could not get my ship to survive past a few capital ships because the repair bots work so slowly.
uhh... major glitch. i had about 14 lives left and i killed an egg. somehow i had 2 lives left all of a sudden. any reason for this i should know about?
boss stage is way too long. i hit him about ten times and he's still going? why? there's really no reason for it to be this hard. and i know this isn't up to you, but the "hard" badge should be an "impossible" because of the amount of time involved in earning it.
i got to the end of the last level when it froze, and since i wasn't level 6 i couldn't beat the level to come to the menu and save my data, so i have to start over. good game, but the level 6 to win thing is stupid and the freezing -> me having to restart is uber lame. these two problems detract from the game enough to give it only a 3/5 instead of a 5/5.
grrr. skill should be the important thing here, not luck. i can tell i'm getting better as i play, because i get higher and higher every once in a while... but then i'll die on occasion after about 40 enemies due to lack of health, or getting shot from offscreen, or lack of ammo, or, the worst, a glitch of some sort.
more health drops necessary. or at least more consistent health drops. i got about 4 in a row when i only really needed one, then had somewhere in the range of a 5 minute drought, causing my death at around 120 kills.
how the heck are you supposed to make it to wave 40? do you ever get fully healed? i made it to wave 5 and died (yes, pathetic, i know), so i'm just curious if you ever get healed at some sort of milestone level, cause if you don't, i can't see how it's possible to survive.
some of these minigames are awful. controls are way too sensitive for some games, and not sensitive enough for others. i'm only still playing this cause i want to get the badge. 2/5
level up system is horrible. why do you have to move down a level in order to level up? it's cool to make the items get better with level, but characters should be able to level up independently of the floor you're on. 2/5
difficulty curve is ridiculous... i didn't lose a single match until i got to the final mission. i've beaten 5 challenges and the rest of the missions on my first try, and all of a sudden i have to rely almost entirely on luck to win and hope he doesn't draw a creature i can't kill due to my excessively crappy draw. good game, it's just that the last mission is a little bit too luck based for my tastes.
