Hello!
It's great to see your project coming along nicely! I gave it a try and here's some feedback:
1) I love the pixel art!
2) The gacha animation is really nice!
3) I couldn't start the quest mode. I think I have to click a button to start it, but it's probably outside the visible area in my screen. (ultrawide aspect ratio). I suggest adding a way to change the game into window mode or arranging your UI elements to make sure they are visible in any aspect ratio.
4) When doing the gacha, I saw a bunch of square symbols where I'm guessing Japanese characters should be appearing. You may have forgotten to include the font assets.
Sadly I cannot give more feedback until I find a way to start the quest mode.
I hope you can make the adjustments and I'll gladly try the game again!
Keep up the good work!!
