Hey, Thanks for playing our game! Appreciate the kind words. The basic (easy) enemies and shooting was more to on-board the player to the expectations that this game is a typical shooter. This would allow us to add mechanics later on which the player would assume to be standard, but be surprised by their true effects. Which would make the player's intention and their resulting effect be different.
As for the getting stuck bit, I've just uploaded a walkthrough video if you want to see the rest of the game, or perhaps play through it again yourself!
