Thanks for playing, DJ! I appreciate the in-depth review and I took notes on your suggestions on how to improve the rocks + gameplay in the finished version.
The story of HH:DED is an indirect sequel to last years Harold Jam entry 'Harold VS Reid: A Culinary Quest and the Golden Kitchen Knife' that took place in the Haroldverse. The story was a parody of Isekai anime, Dragon Quest and MasterChef.
Hammer Harold is a parody of 90's Sentai anime on the surface with some sci-fi/occult themes mixed in. So HH:DED takes place in a different section of the Haroldverse. It's like one big randomized dimension, unique to each Harold.
TL;DR: The story will make more sense in the finished version but, both Harold's cross paths in the real world. Then Hammer Harold gains access to the Haroldverse using Marsh's Portal Gun and hacking skills to bypass the firewall.
That's the context behind HH and the opening cutscene.
