Thanks, that's part of what I was going for, using some old school games as part of my inspiration. The full game will be a bit different and have some variety with the mechanics. I agree having the player be able to aim with the mouse would have given more control and made for a better experience, I think.
Restricting the player from being able to just shoot wildly is something that I really like. --lost my train of thought here Haha-- But anyway. In the full release, I am going to see about including a multiplayer feature that will have friendly fire, so more incentive to be careful with your shots.
Thanks again for the feedback!
