Needs some work obviously but its a start. The graphics are the best part, it feels like there are more interactions that were planned for the game when you interact with the animals but nothing happens. For a Unity game it would be great to enable the full-screen mode. Keep working and learning and you'll continue to improve. Great start.

I liked the art but found it difficult when jumping since I can't see what I'm jumping to.

I enjoyed playing the game. However, the screen resolution is too small to see where you have to go sometimes. I also noticed that you can't make some jumps all the way at the top part, I don't know if this was intended. I still liked the level design  of having to jump upwards, it gives me the vibes of games like climbing over it. Over great submission!

I liked the pixel art you made! The color scheme is great and the player animations are great. 

Assuming you're using Unity, I'd recommend playing with the cinemachine camera settings so the player doesn't go too far from the player. 

WebGL version doesn't have a full screen option so the player leaving the screen is pretty frequent.

The player feels a little floaty, maybe increasing the gravity after the apex of the jump would feel better!

Overall great work!

The controls are well polished, beautiful pixel art
