Quite impressive for a 'first'!
The sheer amount of work to make a multi-map pack... my respect.
The maps themselves: well, i can see the learning curve. In general, the earliest maps are blocky, have bad lighting, bad texture alignment, are a bit oversimple, some have the same plot line and so on. But they are gradually improving, and the imagination is there!
Allow me to suggest that You find 2 - 4 beta testers; then go through the maps, one by one and get them improved and/or debugged. Some input from friends can really move stuff.
I'm very happy to have You in the mapping community, and i look forward to see ver.1.0 !
Thanks for all Your work, and thanks for sharing!
I appreciate your comments about navigation and polish, and those are definitely areas I'll continue working on. I luckily found someone doing a playthrough on Youtube, so I have some idea where more direction in needed :) As for the boss fights, I can understand they won't be everyone's cup of tea.
Thanks again for taking the time to play through the pack and for sharing your thoughts.
