Wow!
This game is beautifully made! This feels awesome and the graphics are delicious!
It would be nice to have a clear anticipation of what's going to happen. For instance, the jump button changed to I, but I had no idea that this was going to happen, so having some sort of animation playing to present it would have made it a little bit more clearer. But this is definitely nitpicking.
This game is stunning, especially for being made within one week.
PS: If you make another video, feel free to include my project.
