Seems promising but needs a little bit of flashing out:)

During the tutorial, the automatic advance-to-next level sometimes gets in the way - at the speed zapper level I wanted to debug if I am using the zapper at the correct distance but the level is finished so fast that I have only few seconds to read the debug messages.
It also seems that I have been sent to a different tutorial level from the zapper one as, clicking back goes through minotaur and few others that I haven't done yet.

Switching from in-game script to API tab or other way around, always starts the program which felt a bit jarring.
A global start/stop seems better to me, as well as being able to pause everything with space key.

Finally, one thing I would love is being able to "debug" draw symbols (lines, circles, ...) similar to how oort rs web game does it, would help a lot with debugging 2d stuff:)

Very good, use it to learn!
