Really ambitious for a solo dev's first game jam. Congratulations on completing & submitting a game! Was fun to play although if no one else had commented I wouldn't have realised I should try dashing as a ghost to phase through the gate, I thought you'd just run out of time and that was the end for a moment. But I got to the boss fight after that! Similarly, on my first run I immediately killed all the monsters before realizing I needed them to kill me. The enemies were very slow and not very good at doing much, haha. Another issue was that the hitboxes felt off; it often looked like I was hitting them or they were hitting me, but noone was taking damage. Still, though, was a fun little game. Huge project to take on for your first jam. Great job.
