I liked the music and the level design is good. Quite a challenge to finish the game. I played the mobile version and there is a problem with the jump and walk left button. Only part of the button reacts and the rest reacts with about half a second delay. This made the game drag on for at least an hour and I was quite frustrated.
I really died a lot in the game. :D
In the caves when I jumped where the upgrade shop was, it bought me extra heart even though I didn't have enough crystals. I'm sending a photo where I have minus crystals after what happened to me. I have not been able to replicate it elsewhere. on the screenshot I marked the parts of the buttons that work correctly and the rest with a delay.
hopefully it will help to improve for the next update. Really looking forward to more content. 🐱
PS: Maybe in the future it would be good to add an option to skip the intro when replaying the game. :)
