After trying it a few times, I realized this little bug could probably be optimized. If the S key had a higher priority than entering a phone number when making a call, I think my gameplay would feel smoother. But in any case, congratulations on finishing the game!
Hello, and thank you for your feedback! The reason you are stuck is that when you click on the phone, you must enter a number to call. If we had had more time to playtest, we would have realized that adding a way to escape from this input would be beneficial to the player. Nonetheless, we at BombCo.™ are so happy you enjoyed the game!
