If you want to make a full game, or customize the graphics, audio, or code, then you should be using Hello Engine Instead. You thought it would be a higher score? NO! It is overshadowed by Game Master, Mario Builder, and SMBX! Those 3 games are more accurate to the gameplay and allow for you to add custom blocks if you want to! Sometimes the sounds sound like my GBC to where you can hear the songs but with a screeching noise.
