"expedition complete shutting down connextion"
After I realized I could keep 'Q' pressed it flowed and I had ton of fun playing the game.
I dig the presentation, the art is super cool.
Movement is not perfect, you kind of have to time your button presses to move smoothly. It's also a bit slow but I guess it have to be because of how enemies work.
The concept works and the provided map is exactly what you need to progress. I really like that the enemies are vicious.
After finishing the first level I feared the game would get repetitive but the 4 levels are actually quite good, for example from the 3rd one I started to appreciate building walls, while before that I did not see the point. In the end I think the scope you went for is perfect.
Congratulations.
