I'm glad you enjoyed it!
A targeting reticle is actually an option in the game in both: the main menu and the pause menu. As for the movement, I realized that the web build and the standalone build were behaving differently and I should have made the rotation faster anyway, but I only caught that when there was no more time to change anything.
Also, yes there is an actual ending. You're supposed to follow the black objects left on the ground. I had the game play-tested by some friends and finding the way to go never seemed like an issue, but with sample size of 2 I should have been more diligent.
Thanks for the detailed review!
