Hey, GigaElk. Just tried your latest build and what an improvement from the jam! I like the ideas you have. I know you had planned to move onto a new area but maybe you could expand the intro area with a few more puzzles revolving around the pipes and water mechanics. They're cool ideas and definitely should be expanded upon.
I really like what you did turning down the opacity of the main character. Such a small thing really helps with selling the theme. Great work! Can't wait to see more progress in the future!
