I read comments from other people, who didn’t read the description before playing, state that when they spammed the laser, they quickly stopped because they found out that the spamming was very expensive in terms of how many points they lost (more than they got back from stopping the aliens).
To me, this is proof that this mechanic serves its intended purpose: To make players think about when they shoot instead of just shooting endlessly.
I put this information in the “Strategy Guide” section of the game description because it’s slightly more advanced information that a new player does not need to know immediately.
In my opinion, not all game mechanics need to be pushed to the forefront, because if they were, it’d be overwhelming.
