I think this game's strong points are definitely in its battle animations and action sequencing, which is good, because otherwise, I found the battles to be a little unfulfilling -- since they are either incredibly unbalanced (in the beginning of the game) or, as you progress, you have so much HP / MP that fighting feels pointless. But, at least you have something nice to look at during them. The mechanics of the battles are also passable, but they're nothing super unique or impressive.
I think some of your mapping makes it challenging for the player to figure out what they should be doing / where they should be going. I like the puzzle idea of having to move rocks and cut trees to navigate and avoid enemies, rather than a tried-and-true stealth puzzle or a generic maze.
Some of your gameplay elements could use a text prompt to nudge the player in the right direction, rather than having to guess-and-check for their next steps -- or in the case of the torches puzzle, maybe an indicator to read the stone tablet or bring the player over and "force" them to read it the first time, just because it's the first puzzle and you want to set up the correct expectations.
The translation is definitely a little rough in parts, but I couldn't imagine creating an entire game in my second language, let alone under such a time crunch, so I commend you for that -- just keep in mind that you'll want to find a native speaker to proofread and help with the translation if you opt to continue development with this one.
