Dunno if anyone on here has used this site but I can recommend it for introducing kids to chiptune songwriting. I’m currently using it with my after school class of 8-10 yr olds and after 1 session they are creating some really good tunes!

Worth a play I reckon.

Oh yeah, it runs happily inside my phone’s browser so if I don’t have the arcade handy, this will satisfy my chiptune cravings on my commute!!
