I always love Chargin Chucks getting a little more love!
This is a pretty nice level, kinda feels like one from the original game. I have a couple of nitpicks, though:
You could probably move the ? blocks higher; this first space was a little cramped.
This Spiny at the top of the triangle block ledge is kind of unfair. If I hadn't noticed it right away, it would've run right into me.
Other than that, though, I think it's pretty good!
