Nice and fluid movement and I love the old-school aesthetic. The combat system was cool but I wish it was explained a little bit better. It took a bit of trial and error to figure it out and I'm still not 100% sure how it all worked exactly.
There was indeed a lot of void space but not sure what the other comment was about having a hard time finding the dungeon. Other than facing the space ship when you start, even if you go in every nook and cranny in the initial area it takes all of 60 seconds with how quick you can move around. The big pillars with the large glowing portal seemed pretty obvious place to go but I play alot of games so maybe it's not intuitive to certain types of players.
