Hi Theor :P
I love the atmosphere of the game! It had that spark create some curiosity within the player. The visuals and audio complemented each other very well to create that immersive atmosphere. I also just love minimalist games :P They're all quite pleasing to the eye!
I wanted to get all the endings when I saw that the ending I got was ending 1. So I played it multiple times, looking for hidden buttons and spamming left click on everything, but only got ending 1 and 2. Perhaps a few subtle nudges towards the endings that are a bit difficult to get would be helpful to players like me :P
Overall it looks fantastic! I just wish that moving platform was a bit less buggy :P
