Thank you for joining the Graphics Community. I can help with your question.
Bear in mind that the game requirements indicate that is needed 2 GB of video RAM, and the Intel® HD Graphics 4000 can only allocate up to 1.7GB. You may try the following driver: Download Intel® Graphics Driver for Windows* [15.33], and you can use these steps for the installation: Manually Install an Intel® Graphics Driver in Windows® 10 and..., but any issues with the game are expected.
