First impression - allow people to disable the walking bob. The slight side to side bobbing, even on the start menu, caused instant motion sickness for me. I managed to play to the first enemies, but quickly gave up.
The game looks gorgeous. Maybe some sort of music could have started earlier? Also, having controls listed in game would help. I had to stop and look at the game page to find out I could actually fight back.
Well done for two weeks though. This looks really pretty! Just needs some more polish and some accessibility options!
