With GWJ's strong push for accessibility, we try to accommodate as many input types as we can. Even our games before joining GWJ we tried to be accessible, so it was a good fit for us.
I have to admit, mobile is often the last tested, which is why I missed adding a drag and drop mode for it, and had to settle last minute for throwing in some notes about how it worked when I realized it was not intuitive. I did mange one fix for it before submissions closed. By default, as soon as you click/touch the tower in placement mode, it would place the tower. With mobile, if you tried to click on the tower to drag it from the start position, it would instead place it there, which was not ideal. It got an update to require movement before placing.
