So I have played your game for about an hour or so and I would like to share my experience and provide some feedback.
Graphics: Very nice graphics in the game, like the gore and kicking heads around. The cut scene graphics could do with some improvement if you would like to release this officially but for what it is, it looks great.
Love the effects, and the fluidity of the animations
Sound: The sound effects are high quality, sound when you walk in water, when you walk on dead bodies, just great.
BUT I cannot get over the music, sorry man, it just does not feel right to the situations. The Dynamic music does not change when there is a battle, I did get my adrenalin pumped up while fighting 4 knights that I could only knock off and then shoot and had limited mana to do that, but the music ruined it for me. Either something more 8bit or more orchestral music would be cool.
Game-play: Now, where to start. I like the skills, love the interaction with the objects using the telekinesis in combination with my attack. Loved to roll boulders on enemies or throw fire from the fire pits at them. Loved to activate the traps and lure the enemies so that they get destroyed. Overall the interaction with the environment is great, I can say that it feels very professional and made me want to play the game more.
The learning curve is good, you have enough time to learn the skills and how to combine them to get a result. It took me 2 deaths to figure out how to kill the heavy knights, so that was very fast and intuitive too.
Now, the light seems useless, never used it as well as the second skill, just left click attack and the telekinesis.
Also the mana depletes just too darn fast, don't get me wrong, I like challenge, but some way to replenish it - maybe in the ponds or fountains? - would be great. Also the loot from crates and chests would be great addition as after a while I did not bother to shoot them anymore as I wanted to preserve the mana for enemies, I see that as a opportunity missed form the point of a player interaction, some loot like health or mana refill would be nice. I just found myself running out of the room, then back to deal some damage, then out again, reverse repeat until all enemies were dead.
In the puzzle room where I found the key, I just had no idea for about 15 minutes where to go, some indicators would be nice as I gave up after that and started the game over again to enjoy the combat
Maybe something to think about.
Overall: I don't know if you are a professional dev or just a person with good taste, but this feels great. The game play is fluid, the combat is impact-full (if you ignore the music). The attention to detail such as fire spreading, tables flipping, ability to "throw" the fire at enemies, use tactic during combat... all great. The story line seems quite generic but it is not bad, just "expected", which is good in a way. With some updated music and cut scene graphics I can see this passing Steam GreenLight, hell, I would love to see it there and give it a big thumbs up. You need more social presence and marketing my friend. Overall, one of the most finished and polished games that can be found on these forums.
Feature request: Leveling of the spells, maybe "learn" new spells, make the light relevant for some areas, more interaction with the environment (the falling tree at the beginning for example was great and I hoped to see more interaction like that), some loot from boxes..
I hope that this will be helpful to you for your further development of this project.
Keep up the good work!
