Thank you, i'm glad that you liked my game! Aslo i'm think level design is big problem, because i was making levels in a hurry a few hours before deadline). So this leads to problems such as bad item and enemy placement, small size fo the maps. Maybe after the jam i will make new levels. When I developed this game, I wanted to make 5-8 levels to feel like a completed episode (like episodes from original DOOM) but time has set its own conditions)))
