Agreed with BiggestBoof - the opening cutscene to this was so sweet. Really appreciate the effort you put in to giving the game a bit of a story!
After that, I felt a little lost; like I was just sort of swimming in the dark for a bit, the walls were kinda hard to see and it felt like I was already doing something wrong haha. Weird that you have to do that before seeing the controls; would have been nice to see the controls sooner maybe?
Having said that, a very cool and unique take on the theme. I love the gecko's movement - though it can be a bit fiddly at times, it's really cool how his tail moves & how the movement changes based on if you're swimming or not.
Great entry, really enjoyed!
