It has come to my attention that at least one user has received a game-ending error message when solving one of the two puzzles in the game. This particular user was running the game on a PC with low specs, which may explain why the error occurred for them and not for others. If you happen to experience the same issue and are interested in completing the game, I recommend skipping the puzzles, which can be done as follows:
When solving either of the two puzzles, a '?' icon will appear in the corner of the screen. Click the '?' and, when prompted, select the option to 'let Tom take over'. (You will need to confirm your choice by clicking it again when prompted a second time.) This will allow you to bypass any potential game-crashing bugs.
Thank you for your patience, and I hope you enjoy playing The Basement!
