Thanks for the feedback and glad you liked it.
I agree the background is a bit bland, I was looking for something to put there which wasn't too noisy or distracting for the player but I didn't manage to find/make something relatively quickly so I opted to drop it in favor of assets I could finish relatively easily.
As for the laser pointer, we really regret not turning that thing on by default. Everyone who we have seen playing or heard feedback from so far turned it on as soon as they learned of its existence.
The hitboxes are already a bit bigger than the enemy sprites would suggest, and I felt they were quite fair, but then again, I've been working on the game semi-non stop for 2 days so I probably got used to them in playtesting.
The cooldown mechanic is certainly a cool idea, but I'm personally quite fond of the system we have now. I might be slightly biased in that though. Should probably discuss it with my compatriot.
