I played against myself and on the same machine and the networking seemed to work.
The mechanics of pushing and pulling are easy to understand and give the potential for a lot of fun. 
The game has a very cool art style and nice animations, especially going up the tower. I like that I can over the grass and flowers to flatten them - a nice touch.
The character falling to his back and getting stuck happens when very close to the edge. Other than that the game seems to be working well! Just be careful about players joining with the same name. Great work!

Love the artstyle and the music, it's so appealing. Couldn't get the port forwarding to work, but I played alone for a bit and the concept seems solid, using physics is a fun mechanic. Did get stuck on my back after a while and couldn't get back up, but overall a really nice setting and atmosphere!

Unfortunatelly couldn't play it but I LOVED the artstyle and music. I bet it would've been fun!
