Haha, I'm right there with you, on that. I kept finding myself wanting to add in a whole bunch more things, and reminding myself not to over-scope the game within the time limit of the jam, and instead to execute the basic idea well, and then polish it up for presentation. With more time, and a team to spread around some of the work, I would definitely love to have a variety of enemy types, powerups, progression, and so on. Thank you for playing my game! ♥
