Thanks for playing! Glad you enjoyed it:) The enemies are placed in such a way that it's hard to get around them without trying to shoot them. Yes, the platforms are such that it's not too easy and boring. The runs are short too, so as not to bore the player, and it's clear from the story why everything is repeated from the beginning.
Oh, that's a bug I had a hard time detecting. Which is why I couldn't fix it. Usually if you repeat the ending the text should become normal (ideally restarting the game of course).
There are five endings in the game, if you get all of them, it's awesome!
