You always come up with some of the best ideas out of such simple modifications of vanilla resources!
I recognize those On/Off Blocks and Note Blocks from your hack "Of Jumps and Platforms", and to be honest, they're such a good idea i can't help but wonder how did we need to wait until 2020 to have them become a thing!
Also, those sprites are really good twists on vanilla sprites! Both the Blaarg and the Bony Beetle make for an excellent added danger that their vanilla counterparts really needed!
I can see a lot of interesting and challenging levels coming out of these two!
That Bowser Fire is also a pretty cool hazard, and i like that it hurts Mario even when spin jumping, since spin jump in general is a very powerful ability that allows players to skip through a lot of hazards. Although i do see a problem in communicating that to the player, since these sprites are identical to the vanilla Bowser Fire, which can be spin jumped on.
