For those who did not get the badge. simply play again and die and screenshot your "current highscore" and report your badge missing with said screenshot.
._.; This game is quite fun, but just... being unable to get that last star for not having enough money on levels where the money seems to be slightly random each time is not having much forthought. It helps to let enemies spawn from iglues some of the time but some levels don't even have those.
Just... wow: Getting every upgrade means that when hiding in your base, it can beat every level but 38 and the final level on it's own. Just leaving your maxed out tank in-front of the base where it spawns lets your base beat even those two levels despite absolutely no input from you. You really do become indestructible >.>;
Just a random idea for petals that I'm sure many have thought of that help for all those who play this game way to much with nothing more to spend on.
Stats:
Starting Boost: how far ahead you are to begin with (this is really more aesthetic but hey, it's something!)
Sight: gives you a slight prediction of what's ahead that's improvable
Let stats go past current caps... but at double the cost for each 1 point. (This will keep grinders happy for a long time >.> Perhaps having them turn green instead of orange for each point so high)
Aesthetics:
Hats (already suggested and planned. :3)
Colors and Patterns
Clothing
Hub Accessories (making your screen look prettier, like a speed gauge with different looks and such)
I'm sure there are a lot of possibilities for this game. XD
a fun tactic for 1940: have both plans fly forward, but then slightly towards each other so they target the opposite dusters. Then have both planes uturn so they start chasing with out crossing the poison case, and just have them fly in a helux with each other. Neither will get hit by the poison and will keep alternating targets... it's quite cool to watch.
hmmm... I wonder why Helix got so many negative votes, sometimes I wonder if a few people just auto downvote and auto upvote after certain points in either direction.
With how wonderful a finished working machine... well, works, I'd love to be able to save the final result, either to a file on the game or just text I could store somewhere.
A great tactic for getting speed is trying to get behind him as he fires his lasers and attacking away for massive combo + EXP, this helps you get a lot of exp to level fast as well as some good quick free damage... the first time I'm saying this but + if this has helped you.
