Well I gotta say I didn't expect that ending.
The first area is great at feeling peacful and I like the voxel art chickens. The tonal shift to the second area is definitely a surprise.
I found the sprite rooster enemies with the rubber chicken noises funny, so good job on that!
As for the movement, I think it needs a lot of work. It's slow, requires individual keyboard presses which gets tiring especially with how slow the movement speed is. I also got off the grid in the first level, I think the code for turning or checking if the turn is complete needs to be looked over.
The combat is actually a little interesting, having the block mechanic does make combat a little more involved than just clicking until an enemy is dead. I genuinely don't know what the blue bar under the health is supposed to be, I'm assuming it was meant for the players block ability?
Also I think there's an opportunity for greater tonal shift in the second area by having some eerie music or ambience playing in the background.
Overall there's definitly areas for improvement, but ultimately I thought this was neat. Good work!
