A'ight, will do, thanks. c:
@Maylene: I see what you're on about, though it's supposed to be hard. I like a good challenge myself; not one that destroys you without any progress on your side (which might be the problem you're facing), but one that does take more than two brain cells to get through. Easy games are good for some people, though i'm not one of them. When i fight a boss, i want to feel like it's ME defeating it, not the game doing it for me. The bosses here are a reflection of that; you do need good stats to beat them, but player skills also contribute quite significantly to the defeating of them. Likewise with the levels, though not quite as much, since a lack of firepower will result in less cash. (so there's a tip, go more for offense than defense)
It's a really delicate balance; the difficulty needs to increase as the game progresses, but at the same time, the players ability to cope with this difficulty also increases rapidly. Making the player not feel overpowered or stagnant is critical, because a lack of progress/challenge is a quick way to boredom. Thus, the very steep difficulty curve. Some games have the players reach ridiculous levels of power near the end, where they can absolutely dominate every opposition ever. I want to avoid that (for the most part), because while it is fun to be god tier for a while, it quickly loses its novelty. Therefore, the very final boss will be a significant challenge, even with full upgrades.
HOWEVER, i agree with that green wall on level 9 being hard. It IS a complete bitch sometimes, because it can be really hard to wipe quickly enough to avoid major damage (i fell to that myself while playing on Nightmare). I'll have to tune it down a bit, though with that said, if you can't handle that wall, there's no way in hell you'll ever beat the second boss at the moment. :U (or the finale of level 9, which is worse than the wall but easier than the boss)
It was an uninspired addition, i admit, because thinking up novel encounters is getting progressively hard. It's unlikely to be the last of such, but that's why i keep making all these alpha versions for you to test. c:
As a final note, do remember that there is an Easy difficulty. It should make surviving much easier, since you take 40% less damage from everything. I included it specifically because some people might be overwhelmed by the baseline challenge set by Normal, in a feeble attempt to broaden the audience. The only disadvantage to Easy is a lower score, which only affects bragging rights. Cash and XP both remain constant through all difficulties.
@torismaser: Well that's farther than me, i only bothered to complete the first level. :U
As for the suggestions, i was actually thinking of including beam turrets in the later levels, though as Maylene mentioned, they could potentially fuck your world all the way through the nine circles of hell and back. It'd definitely need some kind of inaccuracy, because else it's just a countdown timer to your death. Green beams aren't so bad, your shields can take them. Yellow beams... Not so much. What there will be, however, is turrets firing the big fat lasers. Slowly, of course, since those lasers are insanely powerful. Probably only in the levels 15-20.
Also, invisible yellow wedges? That's just too cruel. I want to challenge the player, not destroy him/her (too many times, anyways). :U (and besides, there will be plenty of annoying meatshields post level 10)
@JellyNinja: Thanks man! I will, don't worry (if you'd ever do that). It might be slow, but as Confucius says, it matters not how slowly you go as long as you never stop. (or something, sounds nice for a lazy ass like me regardless)
