This game can store inventory from items you collected, and you can buy, sell, and upgrade items. Can you built games like this with construct 2?
Yes, any 2D type of game can be made with Construct2 if you put enough time and effort into it.
You would have to render your assets to have the "3D look" like in this game, but otherwise, nothing that can't be done.

Develop games in your browser. Powerful, performant & highly capable.
Nicely said :) personally never found any limitation except 2D graphics and single-player games, but of course even so there are work arounds to that, so with Construct I always think of the idea and just go ahead with it!
