I think it's a really good starting point for a nice game. The idea of the the day and night cycle is interesting, I liked how you used different patterns to create variety. The combat can be improved I think, maybe making the weapon stronger or the enemies have lower health. Being able to hold down the mouse button to shoot could also be a nice feature to have.
A thing I really didn't like was the hint at the start of the second level, I get that you are trying to teach the player the mechanic but telling them what to do removes the best part of a videogame, choice. I think only saying the direction of the spawning enemies through text or better with ui elements would be much much better.

Thank you very much for playing and for the detailed feedback. I also find the combat a bit too slow; I have the option to adjust the strength, attack power, and speed of the enemies, which I've already used in the levels, but it’s not quite balanced yet. The suggestion about using the space bar is a really good idea. Regarding the help texts, the first six are indeed very specific, as it's meant to be a sort of tutorial—maybe I overdid it a bit :-D. From level 7 onwards, it becomes much more general. Thanks again!
