No worries, good tutorials are always hard to make in such a short period of time, now we know that we should spend more time on one for the next game jam :)
Okay I managed to get further this time.
I still failed quite a few runs on the first and second levels with only 1 health but once you pick up momentum it becomes a lot easier.
I didn't manage to beat it though. The last stage got really laggy and the game crashed when I died. This is just game jam stuff and I don't blame you for it.
Much better now I know how to play :)
