It is really good and fits the theme of the jam very well I think.
The only aspect that catched my eyes was that the level requirements/exp are set too high. Expecially in the later levels, I was just rotating the mouse forever until I got enough exp.
But it did take a little bit too long for my taste. Maybe consider making the update cost increase by 1 rather than 2... and having wood, stone and leaves seems to be a little bit overkill. I think wood alone as a resource would be sufficient.
Very cool platformer with nice art. Sometimes it's a bit frustrating when you just see an arrow pointing in a direction, but you can't really see where you land. Otherwise: Noice!
First of all, I played until wave 30, so it is a very fun game. But there are a few problems:
I can only click the text on the button, not the button itself
The pixel resolution of the characters is different, and the art could be better or more consistent in general.
I don't have the feeling that the characters are balanced right now. The axe man feels overpowered compared to the others, and the mages are too weak I think.
I think with so few pixels, the coolest thing in my opinion would be to have a pdf manual like with old games. Otherwise a info screen or two in the main menu or somewhere would be nice, yes.
A little bit of luck is involved. Besides, I should have explained what the different Colors do really. Did you realize that your green vertex/Vertices represent your life total?
Quite the interesting game mechanics because the difficulty is self-adjusting. I like that. The voice acting is impressive.
It bothered me a little bit that you mixed quite some different art styles, which comes a bit strange(the portraits). And the red exclamation mark warning should be a second or two longer, otherwise you can't evade anyway. Maybe you could even change it to the color of the upcoming ship.
