Aligning the item stat boxes and coloring up the stats (red - worse/equal, green - better) would be nice improvement: Here's a mockup that include the missing stats too: https://imgur.com/a/nN9zyWh
If you make the mistake of trying to grind the characters to maximum lvl before trying to play the last level in Hardcore mode, you're going to have a bad time ;P
I wonder if that badge was added before some tweaks that rendered it impossible? (Do you really want to restart the mission - No, I'd rather never play this game again, but I have to. Again.)
Did you skip the intro? The guns stopped the aliens, but they keep reanimating! thus poison after killing! :P Completely logical. Needs +speed up upgrade.
Towers except boulder and spear are useless. Traps besides frost are useless. all pets besides the one that drops flying enemies are useless. skills power walker and defence? oh please... this game needs tuning... controls also a bit clumsy. Castaway Island was a nice game, and this could be one too. A little honing is all it needs.
Interesting hard badge. Not because the game is hard, but because playing sucks so bad it's difficult to bother...also, gotta have all the cliche weapons because they are so cool, too bad they are all useless.
