As soon as your sting hits level 5, the impossible badge will be doable. To be honest, you could do it before then if you have good items but rank 5 is where I first tried and got up to nearly wave 60. I'm still nowhere near the hard badge though.
This is a decent enough game, but the 'idle' part is a bit of a scam, if you click off the window the number stops going up. I went to the toilet and came back to not having made any progress at all!
The coin gains do not scale very well with mob level. When I stalled at level 30 I was gaining coins faster than I am now at level 70 because it's taking longer to kill stuff but I'm barely gaining more coins
This game makes me wish there was a "mobile port" and "Micro transactions" label so that when greedy devs brought their games here we can know about it before even clicking on it.
'Blacky' screws me over so hard. I find myself fighting on four sides, just barely managing to pull some epic comeback from being fought into a corner, just to find that 'blacky' has taken over half the screen and now you're screwed. Once he came in I got a bit bored because he's so fast that he can destroy all of the enemy within minutes of appearing, yet I struggle to beat the AI on the later levels full stop so I then gave up but up until that point it was quite fun
A $/minute or $/second on each of the investments could be a nice feature too, I'd like to know which of my investments is bringing me in more money per how much I'm spending on it.
Bug report, I got afflatoxin put on a retrovirus I owned so I used it's ability so it would die and not turn into a malignant cell, when I then placed a graboid down in its place it instantly turned into a burrowed malignant cell.
I usually love the creeper games but I seriously dislike the experiment level, a speed run is not my style of play in creeper and being forced into it just made me quit the level before even trying it. My main love of the creeper series has been the flexibility of how you can head towards a mission and mine has always been defend on a small scale while setting up for a huge all out counter attack. It's slow and it's not great for the score but it's my way of playing, everyone does it differently and being forced into running through a level throws my pacing off.
The 'sad story' in the kickstarter is actually a good idea; I went onto the kickstarter both excited and angry, I was excited for a new LtF but angry because I would hate for flash developers to start using kickstarter, it's already too much of an overused concept that's often abused.
Then I read the whole page, it made sense. I empathise with you and I now understand WHY you've done the kickstarter and it's one of the few projects that I agree with, viva la light bringer!
Some of these cards are ridiculously overpowered, mirror force NEEDS to be nerfed or got rid of. The second I see one I put it in my deck because of just how OP it is.
The arena battle needs some SERIOUS balancing, if my most powerful monster is a 3 star, fighting against people whom have consistant 7 star creatures isn't remotely funny.
A way of sorting my modules would be nice, when I get to the last galaxy and I'm rebuilding my ship from scratch, trying to figure out where everything is is hard.
Refresh and regen are quite possibly the two most annoying abilities physically possible. One is just overpowered, if I'm hitting a two health card with 13 power, it should not be able to damned recover from that, the other is just irritating because you have to OHKO the card, even when it's on it's played cooldown.
