Hey! Thanks a ton for taking the time to play my game and for you feedback!
I'm really happy to hear that you enjoyed it; I was worried no one would get past the first area. It's great to know you made it so far.
Regarding adding more sound effects, rest assured that it will be done, and I also want each area to have its own music. I'll be refining things gradually.
I hadn't noticed the issue with the purple door boss (sorry about that). The game still has some design flaws and bugs to fix (many updates are coming post-jam).
By the way, I've been playing your game. I'll leave a review as soon as I finish it, but so far, it's going great — quite challenging :D
Thanks again!
