I think the game could need a little more work, such as the bug in the scroll bar, but for now it's fine enough. I present to you, Elemental v2! Left Arrow/Right Arrow - Scroll LMB - Selected, press again over combination table to place. Press again not over combination table to deselect. Search Button - Click for usage, enter void(don't type anything) for all elements.
This is a remake of the original "Elemental" project I had. In my opinion, this turned out better than expected, and also better than the original. Thanks to @TillingDig75596 for the Alphabet Sorter that I used to sort the elements! Credits to one of my friends for element ideas (they are using an account called @ErrorHC gifted by someone lol), and thanks to myself for inspiration to make a second version.
