Quite fun. Enjoyed farming the big squirrel for xp, then got upgrades and fought the leader of all birds. The bow seems a bit weak compared to the sword.
I reached this room where walls spawned on me and I got stuck. Could not move at all =(
There are some other small bugs like when you die the extra health container is gone while the upgrade is still active so you can't get it again. And when I had 4 health containers and bought the final health upgrade didn't get extra container (maybe just a visual bug).
Overall this is a cool game and a nice change from all spider web stuff =D
Well done.
