The world selection and the worlds themselves reminded me somewhat of Super Mario Galaxy, a game that I really like, so that immediately pulled me in. I also liked the different tools the little robot can use, but, like others have mentioned, it was not intuitive to me that the scroll wheel could be used to change tools. However, after learning this from the comments, I was able to complete the game without any further hiccups, so I feel that this was the only control that actually needed to be explained. The movement is quite intuitive (in a full-fledged game this of course would also need to be explained, but for a game jam game I don't find that such a big problem), and the picking up of boxes and other uses of left mouse button were explained in the UI. Maybe you could also use something similar to explain the tool change, but other than that, I really enjoyed the game and thought it looked very pretty!

Thank you for the feedback, That was definetly my mistake, when you developing something it sounds natural for you what to do next, but I have to remind myself it is not that obvious to others. But this is how we get experience, on my first gamejam I was so stuck to the story which made the game not fun to play, but just listening a story.. Then I tried to correct that on the second, and now I have a game with a fun mechanic but no story and explanation of things haha I just need to find this median point where I have best of both worlds xD
