Of course!

You reach out and press the inventory button on the interface. It suddenly changes, and instead of a menu, you now see a classic RPG inventory screen, with boxes for items and a space for coins it seems. "Wow, this is really cool. I wonder how it works though..." you say as you look around the cave. You spot a few pebbles and pick them up. After pontering how this works for a few seconds, you try throwing the pebbles at the inventory screen, but as soon as they reach it, they fly through it, like it's not there, hitting against the cave walls. "Well, that didn't work." You pick up a few more pebbles and this time you try to imagine the pebbles in your hand going into your inventory. Nothing happens. "Maybe if I close my eyes too." you think as shut your eyes and imagine the pebbles being in your inventory. You open your eyes and see the pebbles still sitting in your hand. "Welp... that didn't work", you say and chuckle. You reach towards the screen slowly, with your hand still full of pebbles, and calmly let go of them above one of the slots, expecting them to just fall through again, but to your surprise, the pebbles light op for a split second, then disintegrate before they suddenly appear in one of your inventory slots. "Huh, so that's how it works, neat."

You press an arrow pointing back on the interface and you go back to the first two selections. "Now, let's check out the stat part. I really hope it's a bit more exciting than my very empty inventory."

You press the button and the interface change yet again:

"Wow, is this for real?... I have unassigned points too... I wonder what it does when I point them in...?" You say with a puzzled look on your face. You feel like some physical traits might be the best way to see what happens, so you dump your points into strength and endurance.

As soon as you are done, you feel your muscles tense up and release a few times, before returning to normal. As you look at yourself, you are certain that your muscles look a bit bigger and tighter than before. You do a couple of flexes and you suddenly feel like you could out-bench every guy you have ever seen at the gym in the other world... or is it actually this world?... Who knows.

You shut down the interface, and as soon as you do, a new transparent box appear before you.
