This is quite the solid game but it has 3 main issues that stick like a sore thumb at the start, and in two specific cases, in every loop, the first one would be the long amount of dialog at the start of each loop, it does deliver some cool "lore pieces" but they could be perfectly be fit with all the other pieces of lore you already have to read due to the puzzle nature of the game, the second issue lies in this two rooms in particular:

It doesn't matter how many iterations i was in, i 6/5 times would faceplank on the wall regardless. or be force to do a sharp u turn, making me waste time, better level design is needed in this parts, the bridge controller is also extremely far away for the amount of times you have to spin it, once you reach the end of the game is a sensible the location, but that's WHEN you already know how to solve the game, which leads me to point 3, puzzles are extremely harsh for such a low timer.
I want to give the benefit of the doubt and believe that the developer REALLY wanted to make it feel like you are running out of time, but the puzzles resetting themselves is already hard enough, and on top of the extremely low timer, the whole level design you have to learn, and the interactions between elements, is a lot of information to digest all at once and in a low time frame, I would had made the timer been 5 minutes and the puzzles reset on player command, that been by a button you can push that resets the puzzle or by leaving and entering the room, the developer even acknowledge this by making one of the hardest puzzles just pause time,which it could had been avoidable by a 5 minute timer and a reset on command instead, after all, these puzzles are disposable, and once you know the answer and got your reward, they are not worth going back to, in this sense they become pushovers rather that problems that you have to solve and that you felt worth solving.
In summary, better map design to avoid your players getting frustrated, manual resets on puzzles and a longer timer since there is a lot to take in, quicker resets to allow me to fail faster and learn from my mistakes, aside from that, is a really solid game with a quick emotional gut punch, and leaves you with many question left unanswered about our protagonist, which i think is a good thing actually, great work for a 4 day game
