Thanks for playing our game. We're glad you liked the graphics and artwork. We spent a long time getting things to look they way they do in game. The underwater part was a key mechanic to our interpretation of the duality theme so we're happy to see you want more of it! You're absolutely right about the sound effects. We ran out of time in the end to add them all in and it was disappointing for us too. We do plan on continuing to develop this game further. Many thanks for your feedback. We look forward to playing your game this week. Best of luck with the jam!
