Thanks for playing!
I had some other people that had crashes too, I'll be investigating the causes and try to solve it and will fix the jump for the next update. The boss fight was made in the very last moments so I didnt really had time to polish it that much, so I threw a couple target points on the room and told the boss to choose and go to them at random while shooting on a timer loop (just to have something for the jam release). I'm glad you liked and thanks for the feedback! ^-^
