Awesome game , there is a huge difference in your first game till this one.... Experience maybe.

and overall you make awesome games.

Congrats on your game ! It's really cool that you created a small space to explore, this way we really have to learn how to dash hahaaa. We also liked that there was no losing state, it makes the experience enjoyable. Also, the robot and the animations are very cute ! Good job :)

Many thanks! =)
