Wow! This was a very nice comment. Thank you so much for your kind words. I really appreciate it. I love working with limitations when it comes to game design. It's weird to think how difficult it is to replicate the restrictions of these older systems. It doesn't seem like it should be that hard. Regardless, I love the challenge.
I have a ton of ideas on how to expand this game. I've already been working on it. I've got a nice CRT screen effect, I've finished designing a fully complete and functional title screen and options menu, the game engine has been greatly polished, and I've set things up to increase obstacle types and level size. I can't wait to share what I've been up to.
