Thanks for playing our game! The instructions were definitely way too overwhelming, and a tutorial would certainly help ease the player into the mechanics of the game. The tooltips feature does sound like a good idea and a better way of displaying the tutorial than just the pictures, and to remind the players on certain mechanics. For now the game doesn't work on mobile, so the amount of space wouldn't necessarily be a limitation at the moment. I can see the confusion with the doors as they do look like the walls, and a minimap would've certainly helped with navigation around the map. The credits was a bit messy and the music does get quite repetitive after a while. Thank you for the feedback and glad that you enjoyed our game!
