A very nice and well made game. For simplicity I will mention the good and bad parts below.
The good parts:
1. The game is very well made.
2. The audio feedback is very well planned and realized (perhaps less so the introduction part with Chronos, which could be heard as if the song kept repeating itself in a loop, but otherwise each level has its own song and the character makes sounds when move or attack and that makes the game fantastic).
3. The UI is perfect, this is especially noticeable during dialogues (I also like that when you start a dialogue with an NPC and if you try to move too far away from him, he will not continue talking until you are at a reasonable distance from him).
4. The graphics of the game are well done and the atmosphere as well.
5. The transition from one level to another is incredibly beautiful (if you can tell me how you did it, if you did it yourself).
The bad parts:
1. The control is unique, but at the same time difficult (it was difficult for me to move by jumping, especially in the level with obstacles).
2. I didn't quite understand how the attack works. When I had to obtain the sword, I tried to attack an enemy who was shooting at me, but after I jumped towards him, he didn't seem to be affected). The fact that you can attack with the "Space" key didn't really help me in killing it,so I used the attack more when I wanted to move faster.
3. I think it's a problem with collisions, because on the very first level when I had to collect 10 coins, I pressed "Space" while I was near to the mountain and the character got stuck in it. Lucky that I managed to escape by spam the "Space" key. Also, in the level with obstacles I noticed several problems, for example with the red moving platform, if you stayed on it after it went away from your feets, the character no longer falls. (I noticed many other problems, but unfortunately I don't have the opportunity to list them all).
Otherwise the game was very good. It is a unique game in my opinion and I really liked it.
