Wow! This was an awesome experience for me! GRIS is one of my all-time favourites, and I genuinely got a similar vibe while playing your game. The atmosphere, music, voice-over, and variety of gameplay mechanics were truly marvelous. The level of immersion was so good that I played the entire game from start to finish in one sitting. This is hands down the best game I played in this game jam!
I have just a couple of minor suggestions. The camera could feel a bit smoother while jumping, perhaps with some damped follow or a better follow target. Also, while the environment suited the gameplay, some of the foreground layers didn’t feel naturally in sync with the character’s jumps, which slightly affected the visual experience.
But honestly, these are negligible compared to how amazing the actual game is. I absolutely loved the experience. Superb work, you absolutely nailed it!
