Nice game! The art and music are beautiful, and the atmosphere overall is well executed. I really liked it!
The main mechanic is a really cool one, but it's a bit underwhelming. Turns out you can just go through any level without it and it'll be fine, since every door and boiler is color/shape coded. I appreciate the effort for accessibility purposes though!
I think you could have pushed the use of the thermal goggles further! Like in combat, or in more variations for puzzles and exploration. Make it feel like a true central piece of the game!
Well done to everyone!
