This game was actually surprisingly fun, much more than expected.
My first impression when I started playing is that it was just a game that plays like Dr. Mario and has a few RPG elements and not much more than that. But the truth is that the game actually has quite a bit of content to encourage the player to delve further into the game - mostly, the new recipes for creating new items, which is pretty cool.
And while Easy difficulty lets the player properly play through the game without much hassle, Hard difficulty presents actual challenge that's not easy to beat (I admit Hard was too difficult for me).
The main issue with the game is that it's repetitive - both in gameplay and in content. Boots and shields will only slow down the falling speed of pieces, weapons can be used to break some pieces, armors are merely cosmetic and pets will fetch items for the player. That's about it. It's pretty fun to try and craft new items but they don't make that much difference in terms of gameplay.
Also, during gameplay, there's a large portrait of your character there, which serves no purpose except show simple animations when the player activates their shield or when the player's pet fetches an item.
The character levels up but I'm yet to see that make any difference during the game. I haven't noticed any differences with my character leveling up.
This game could improve GREATLY by the addition of more, varied content and by making it so leveling up makes a difference somehow, perhaps letting the player add points to attributes that cause an impact on gameplay.
Regardless of these flaws, it's still a fun game.
