Thank you for the review!
I designed this to be mobile first (you can play from the website) where fullscreen works and touch is the obvius way to interact, but I had not thought the experience will be so confusing on computer. I also wanted the player to discover the mechanics as they go, but it looks like needs a lot of work still. And I learned it the hard way, for future jams, sound and music is a must. (Loved that chiptune, haha)
I'll be updating this to a full-fledged mobile game, where it belongs.
Thank you for taking your time playing Vessels!
