The French accent is perfect haha ^^ With the music and the overall vibe, I think it fits well :P
For the gameplay, I think the difficulty is well balanced because I often find this kind of games very frustrating and it was not the case with this one. I tried again, making a better use of the sonar and I think you're right, once I found a good rythm, I went pretty deep while being able to drive the capsule from time to time.
Thank you for your kind words, it's motivating :) Hopefully I'll see you (drinking water) in your next stream!
