The dino grabber does work in the downloaded version. When it comes to the web version, the cake remains on the shelf after being recruited by the necromancer. Although the mouse doesn't pull towards the cake in the web version either. Not sure if that has anything to do with the fact I ate the cake in the web version, but avoided it in the download version.
Overall, great job though! This game has been a blast! I am looking forward to what happens next! :)
