Really cool concept for a game!
It reminds me of games like Superliminal and F-Stop, and honestly this mechanic could be made into a really good horror themed / liminal themed puzzle game!
The atmosphere is great, the look is great and the frogs are amazing lol
I really like that there is no real threat in this game, so it makes your mind wonder what "could" be there, while in reality the only thing you have to fear is yourself lol
An addition I think could be cool for atmosphere (if this game would get expanded on) are text messages from either objects or "someone", that could add a little story or unsettling feeling to the whole game
But all in all, a very good and short game, great concept and feel!
