Contributions summary:Roman contributed to the backend logic of the "icancode" game by creating an abstraction for perks, including timers and availability checks. They defined settings related to perks, such as drop ratio, availability, and activity, which were integrated into the game's service layer. Furthermore, they registered a new "unstoppable-laser" element, implemented the corresponding class, and developed unit tests to validate its functionality, including interactions with other game elements. Finally they implemented the core logic for an 'unlimited-fire' perk.
