Thanks for playing! I've been thinking about both ideas and I really want to be able to do both. I want to be add some sort of save level feature before turning this into a game. Once I do I'll ask friends to design some levels and send them to me because I'm terrible and level design lol. I don't think I'll be able to make something that saves and then automatically loads levels, but I can probably make something that produces a series of numbers and characters that you can save as a text file and that can be loaded by copy/pasting the code into a text box.
While I'm working on that , I'm also planning on doing some research on level design so hopefully I can make a full game out of this. Thanks for the feedback and thanks again for playing this game!
