How to get out of the first room is tricky. Initially, I thought I had to create a word. Then, I realised it was simply an arrangement of letters. Other puzzles are easy.
This was honestly way too easy. There are only two "puzzles," and it's just memory... Well, not even that. You can literally set the puzzle down and it saves what you input, so there's no challenge at all. Three minutes is not an exaggeration.
Quite a fun little way to spend a few minutes, I reckon. Nothing too amazing, but nothing drastically wrong either.
The only qualm I have would be with the font chosen for the hints along the bottom above the inventory. Not only are the letters quite indistinct in shape, but they also blend into one another on occasion, making it harder to read than it needs to/should be.
There will always be some no-life-show-off who will pretend that the game was too easy or that they finished in less than 3 minutes. Don't listen to them. Your game is great! Nice christmas touch :)
