Thank you for the feedback!
I agree with the game start. I initially tried to go about Devil Daggers way, but after seeing their updated new kind of sequel Hyper Demon I noticed that they put a tutorial inside as well, probably for a similar reason now that I am thinking about it. I will definitely insert some kind of tutorial now for the first time playing!
That bug is not supposed to happen! Thank you for reporting that, and I will definitely ticket myself and fix that up for the next version.
Appreciate all the feedback! Also I will def take a look at your game soon :)
