Hey, no worries! And it’s very important because while you're building it things can appear very clear to you, but be completely unreachable for the player. Like the controls and camera: I knew it was not ideal, but since I made it (and have played a lot of RTS), for me it felt somewhat natural, but it's clearly not! I will probably try to switch to keyboard control after the jam.
As for the gameplay, it is going through the randomly generated mazes, trying to find oxygen tanks and the gate to the next level, while trying to avoid and being scared (or killed) by the monsters, to see how long you can last. The number of aliens acctually grows with the level, so the game get's harder. Maybe I should have scattered more oxygen too, specially in the first levels!
Anyway, thanks for playing and the feedback!
