Is this… is this an Armored Tree?
YEP.

And how is that a monster? Is it enough to be an aberration? Or should it slice, burn and impale little birds? (Or not even that, maybe I forced the theme too much, as usual)

Check those bird-impaling skillz
A little post-mortem
Since this is the first game I made since my daughter was born, she is 4 months old now, I planned for a 15-20 hour/work game instead of the usual 30-40 so I focused in the fun part (I love little lander games, always make prototypes but never full games) and thought of a simple art style that I could do myself.
Keeping it short:
What went right:
-I wanted to try pixel art, it was hard to make it look good, but it was perfect to do with only a mouse.
-I also liked how the particles ended, they are my second favorite part of this game.
-Love this kind of game, so I really liked the gameplay
-The multiple ways to kill birds, not as rewarding as I wanted it to be, but I liked the result.
What went wrong:
-The original idea required the birds to nest the trees instead of destroying them (it was a big part of the monstrosity of the tree). Completely forgot about that until the last moments (50 minutes before the deadline the trees weren’t even colliding with the birds). So, no time to add new graphics, just added some ugly ass green particles and called it a day.
-There are a number of bugs (birds that kill themselves count points, forgot to actually destroy the monster-tree when it dies, and the pine-cones).
-The trees are way to blended with the background..
-Sound of some bird deaths turned out weird.
Thats it, if you’ve got a chance to play it, I hope you have fun!
