While the core idea was nice in of itself, I do think the game could be improved on. The enviorments were a bit samey and at times it was dificult to navigate. However I do think that overall it is still a good game, but with some serious flaws.
I also think that you could add some new mechanics to spice up the gameplay and make less hit and run. For example, what if there were enemies that shoot back? Or what if shooting too many lasers really quickly by spamming the spacebar lead to the player overheating and having to stop moving? I don't know, something like that.
Still, I hope you had fun with the jam and that you continue to expand the game!
