I enjoyed this game but I didn't like the flashy lines, they keep distracting me from playing, maybe you can add an option to remove them or make them more subtle, and I also really dislike the spike traps, I can explore the areas with no hit from enemies but then I always get surprised by spike traps, I don't know if this is intentional or not because compared to the rest of the game, it's quite easy so I just found it inconsistent.
But it's still a good game, looking forward to the full game.
