Hey there, i am also having the exact same error on logs from people that tried my demo and had random crash when scene transitioning (can't reproduce the crash myself). Using 4.0 too. What was the cause of this error for your case and how did you fix it?
I wasn't sure if a separate tutorial was needed but i think i will probably add one.
Regarding the aiming maybe it was the spread of projectiles that made it hard to judge? (there is more spread when you shoot with less power). Also, did you click on the question mark on the new run screen (was it visible/important looking enough to click on it and if yes did you find it useful or overwhelming with text info)?
There is already a power up that shows the projectile's path and i am going to add another one that reduces the spread :)
I was a bit aware of the difficulty for new players but it seems i have to tune it down some more. I am probably going to add a small stage tutorial too, to make things easier.
this is really cool but i think it's missing some transitions between attacks and idle cause in attack animations character moves forward but there's no animation to get back to his idle position.
