[2024] Bought TemTem on PS5

As basically title says. The question is: After I played a little stumbled upon the game no receive any content update and there is no future for the multiplayer aspect of it. The 2nd not bothering me, because no one wants to play with me this game (friends not a pokemon\monster collection fans), but the 1st is a little painful for me. I hoped there are new monsters to come in the future...

So... As a singleplayer game how good and enjoyable compared to a Pokemon title? And after beating the story can I collect all the trophies without touching the multiplayer aspect? Final question incoming. If the game servers shutting down in some point there is a chance to play the game offline? Sadly I have a bad habit to freeze a game and jump to another then later come back over it. I little anxious to lose my progress and cannot acquire the leftover trophies.
