The sprite work in this is really cute!

I like the cute pixel art graphics and the general effort spent on the presentation. The game has pretty good UI but, unfortunately, the game is not particularly fine (which is okay). You have a pretty good base but I think you need to consider 'why' and 'how'.

The game has two currencies: health and soul. Why are they physical currencies the character has to pick up when they come from the same place and you get practically the same amount from every enemy type. Why does the player evolve when the new evolution does not have any different to the previous?

The player has to attack constantly spawning incoming waves of enemies, which is completely fine of course but did you consider how the player is supposed to fight these enemies? Enemies can be attacked at infinite speeds. Maybe the different evolutions should each have a unique attack? (the elephant could have a long but wide sweep? the tiger could have quick but thin swipes which can be cancelled into each other but the player cannot turn around until the current attack is fully finished?).

Of course, you should still be proud of yourself for releasing this game. It was still a pleasant experience and it was nice to see what the next evolution was just because of your cute sprite work. I'm sorry for being harsh and I can delete this comment if you want but please don't let it demoralise you. You were on the right track but I just felt like you needed to think about why you were doing what you were doing more. https://www.youtube.com/@GMTK is a pretty good youtube channel for beginner game devs because it will help stimulate that part of your brain.

Thanks for releasing this game and have a good day!
