Okay. So I played this game and here's my thoughts.
What I liked:
The Sprite Work - I think it's really good and reminds me a lot of the US version of Super Mario Bros. 2. You definitely know what you're doing.
I also like how the screen filter is present and looks cool while not obscuring the screen like in other games.
The Level Design - The level design feels like I'm climbing an abandoned castle and I really like as well as the color palette for it as well.
What I would improve on:
Saves - I made it to the final boss and died, but when I died, the game restart. I really wish there was some kind of quick save feature in this game.
Also, controller support would be cool, but I play with my keyboard anyways so that doesn't really matter to me. I'm just saying maybe others might want to play with a controller.
Final thoughts: Overall, this game is a cute, little game with a lot heart to it and a lot of clear passion put into it as well and I can't wait to see the full version.
Final Score - 4/5
