Thank you very much for your comments. We will definitely take these into account and we will fix our game in this way in the future. Also, unfortunately, we have bugs such as moonwalk or jumping problems(because of colliders). We couldn't make it to GameJam, but we will fix these bugs on our future version.
Also, we liked the gameplay you suggested to pick the platform, we will probably rearrange it this way. Thanks again so much.
