Amazing job with this! The puzzles were fun to solve, especially the one where you need to use a wooden box to dive down and shoot yourself up. The sound effects made with water samples are ridiculous, what a cool idea and great execution! I also really enjoyed your humor in the narrative, it made me laugh.
The art and animations were all really cool and slick. The water drain effect especially was really impressive, and I enjoyed watching it for a bit every time I'd solve a puzzle. But sometimes it takes a really long time to drain, especially in the second to last level I felt like I was standing next to the exit for a while.
Looking forward to Aqua Boy's Metroidvania return!
