Version 0.1.5 rel released

Changes:

• When you press an operation that requires entering a number, you are shown which operation you have selected, and it can also be canceled by right-clicking before entering the number.

• Glass buttons have been added. These buttons break upon use and cannot have charges.

• A bug has been fixed where descriptions for some buttons disappeared after the boss battle "You do not see some buttons."

• Typos in the descriptions of multiplication buttons have been corrected.

• In the old calculator, the positions of some keys have been changed for easier use.

• The store now guarantees basic keys for the selected type of calculator.

• The store now sells all types of assignment keys and keys for converting one digit to another.

• An exploit through resizing the window has been fixed, which allowed using buttons outside the screen.

• A very rare version of a bug has been fixed, where identical numbers could appear in the first round.

• Icons for locked buttons do not respond.

• A "swap" button has been added. It swaps the current number with the required one.

• A "prime number" button has been added. It finds the nearest prime number to the current one.

• Bosses removed: "you cannot use ones," "you cannot use sum," "you cannot use twos," "you cannot use multiplication."

• Bosses added: "you cannot use buttons x (number from those you have) and y (operator from those you have)," "you cannot use legendary buttons."

• The amount of money earned per round has been increased.

• A "reroll" button has been added to the store, allowing you to replace all buttons in the store for a certain amount of coins.
