You don't know how happy I was to see that someone actually played my game until the end! I thought no one would notice the ending.
Thank you for your feedback!
Regarding the non stop colliding, you can always press Z to unpause and then pause again on a better position (You wont collide with anything if you dont shot), I don't think it was clear.
I will take it off then, and let you play as many times as you want to get to the objective.
