The graphics are pretty nice and it matches pretty well with your concept. The chicken animations were cute and I liked how the timer was spinning on the chicken.
Gameplay wise, I feel like the collisions could be improved a bit. When landing on a corner, it adds a small bounce to the player which prevented me from doing the second jump I was planning on doing. The corner also stopped me from jumping if I was standing on it. In the third room, it looked like I landed on the platform in the sea of spikes/wire but I still died, I had avoid landing on the corners which made it feel frustrating because I kept dying on the platform. However, I did like how I had to drop down into a wall jump as it felt nice to figure that out.
Aside from the corners, It was fun to play and I mastered up to the first half of the third room. I also made it to the end and got the buzz weapon. Overall, it is a cool concept and had nice art. Great work!
