love the art style and the tutorial, but I didn't manage to scale anything :(

There's a lot of ways to expand this. 

• As far as I could tell, the spiky balls were the only things that could be resized. You could make so many more elements resizable. 
• It was also not totally clear what the goal was, which I know might sound a little weird because you did put a giant "GOAL" sign in the middle of the map, but I wasn't sure where the sign was pointing to since it was right above the starting area. 
• There were a lot of collectibles (coins, diamonds), but it wasn't clear if they had anything to do with the goal. 
• The audio was also peaking really badly. I had to put it on mute. I'm not sure if that was just an issue with my computer or not.

Overall, I think you've got a good core concept and starting point. Great start!

The style and colours of the game are very nice. The mechanics are fun, but it would be nice to have some sort of checkpoints, as it can be frustrating to die and have to start everything all over again. Overall, it is a very enjoyable game :)

Good fun game with interesting mechanics.
