Really nice game and fun to play.
Only thing I noticed: it's possible and quite easy to end all episodes with less than 1/4 of the upgrade availables (killed the last boss with acid gun).
That isn't actually an error, just there isn't a real reason to go up to all the levels.. :)
It's totally unbalanced on different characters.
Red character is nearly boring, having splash damage.
Green character is quite impossible to use after 6th level.
Haven't tried out blue one.. got tired before.
The game has a great idea, but it's poorly balanced.
Story has a great start, but the it fails on the worst levels when you discover what behind the scene.
I know it's my fault but I cannot really catch what you need to win this game.
I'm not so bad on the other Gemcraft game, but I've problem passing 5th level on this one.
If someone have some hints on the game, I'd be pleased to read them.
Note: Strategy guide and other comments are not helping.
my 2 cents:
if the archer doesn't shot automatically ( that's a good idea ) , clicking on a enemy should kill it if in range, or pop out "out of range" without the need to select the archer.
