Thank you for the feedback. The comment about the size actually helped me solve the issue with my web build not building.It was due to the background images not being compressed at all, and there are over 100 images used in total so compressed those and now issue is sorted, so thank you, kind sir. The way I intended the game to work was that a click and hold would be a grab, and just a click would flip the block. I tested it again on the web and Windows version, and it seems to work for me, but it may be something to do with how different mice handle the start of inputs
