Hello,
Thank you very much for the feedback, I'm really happy to see that you enjoyed playing the game the way I enjoyed making it (╹ڡ╹ )
A lot more challenges await in the additional worlds, I'm not going to spoil the fun, but even though the mechanic remains the same (Pushing Sheep is the game's name), different mechanics will be introduced. It's like eating fries, but with different condiments.
The framerate issue is (hopefully) solved in the latest version, I believe the game should run smoothly on a wide range of configurations.
If you have any suggestions or issues you might have encountered during your playthrough I'll be happy to hear them.
Also, don't forget to wishlist the game on Steam to be notified once it's released.
Cheers.
