I'm glad you could manage to play the game! I'll use this info to improve the game performance.
I'm currently developing Tessa's Fate on Godot Engine. I used to code on Unity but, due to personal preferences, I looked for an alternative. I found Godot pretty powerful and easy to learn.
I'm glad you're enjoying the game! Indeed I'm taking inspiration from Hollow Knight. I like mystery and deepness in video games!
I'll be working on performance. For now, I've already uploaded the Web Public version on Newgrounds you can find here:

But, it's a downgraded version, tho.
Thanks for your wishes!
