Nice game! I really liked the level design and difficulty balance, it felt fair and engaging. The multi-language support and fun animations were great touches too.

During my first playthrough, I didn’t immediately realize where to go, I collected all the hearts and waited, only later spotting the portal at the top. I think starting with the fourth level might work better, since the goal is clearer right away.

Also, it took me a while to find the jump key, spacebar didn’t work, which was a bit confusing.

Still, overall it’s a solid game, I completed all the levels, and the music was genuinely good! The options menu was also a nice surprise, especially for a jam game. Well done!

Hi, here is my review:

THE GOOD

I really like the music and the atmosphere it builds. The backgrounds while AI, are still very pretty and I like that you disclosed it. Overall i think it's a simple idea, but sometimes simplicity is the best

POSSIBLE IMPROVEMENTS

The character animation isn't full and it's not synced well with the movement speed, making it feel like the character is moving slower then it should. Also while the backgrounds itself are pretty, they aren't super immersive (as in they don't feel like part of the level). I think it would also be nice if there was a more defined environment instead of floating platforms.

TLDR

I think it's a good prototype, but there is still work to be done for it to be a great game. Definitely achievable though!

Btw, I  would also apprentice if you took your time to look at my own project :)
