I like the minimalistic of this game. No UI but very intriguing. I was also stuck on the laser part with flame and freezing gas. The Brackey's image cube is very funny. Game design wise it delivered to make the player to think how that dying is one of the solution for the puzzle. The theme is clear to see which is the main mechanics (keep dying to solve the puzzle).
Playing for a while, it just get tedious at some point during the game. Maybe it's just me because I don't usually play puzzle game that much.
I hate to say this but the music also kinda gets annoy if you play too long. It was very good at first couple minutes but it too much specially when you are trying to solve the puzzle over and over again.
Overall it was a good game. The intention is clear even without UI or tutorial is very impressive. Good job guys.
