This is a great game! The visuals are good and has good character animation. The character movement feels nice too. The theme fits well and the use of the anvil to craft more platforms is creative.
Suggestions: create more distinct areas to complete so that you feel you are progressing more as you go through the game. Also, I’d prefer to use one button to throw and call back the platforms.
Overall a fun game with a creative use of the special object!
