That was a lot of fun! I did end up getting a bit lost, but it was generally interesting trying to navigate and fight off the endless enemies. I think the problem here was the arbitrary nature of things like 'green 5', which didn't really make for any memorable 'I should come back here' moments. Every time I got a new powerup, I had to walk through the entire area, which did get tiresome. I'm afraid I didn't get the the end, but the game was a great take on the metroidvania genre!
