I still have the old version without checkpoints saved on my computer, so that's what I have been playing.
Here's the first time I beaten the game:
That one time I finished with both eyes:
Here's my best time:
I also had a lot of fun rewatching your game being played on shipwreckdev's stream.
I think it would be cool if you could strategically place eyeballs in some spots. Moving eyes would be cool too.
I also had this idea for maybe a game mode where you start without eyes, and you gotta play the stage without them. Maybe have eyes somewhere for you to collect, and some doors that only open if you have both eyes, or something. I think what you have so far is fun, and there are many directions you can take your game. I look forward to playing more next DD.
