Okay, i have played i think about 20 games in this jam and this is by far the one which frustrated me the most. First off, being forced to play a game like this in windowed mode was annoying but that's ok people can make mistakes. You could have uploaded a downloadable file too though but anyway. Keep that in mind for future jams.
The presantation and visuals of the game looks very promising. You really nailed to capture the atmosphere of Dark Souls visually.
Gameplay: This is where things get messy. The first boss is the type of boss i hate the most in Soulsborne games. It's big and slow but it's accompanied by minions to compensate for the low speed.( Fucking Voracious Spider Rom from Bloodborne. It took me an hour to kill it. ) His jump attack has a very high AoE radius which makes it extremely difficult evade. When you get close to hit, you want to dodge away from it's attack but you can't because the attack animation is too damn slow and it doesn't allow you to dodge in mid attack animation. Not only attack animation, hurt and knockdown animations are too slow as well and to make matters worst you take damage during those animations too. Yes there is staggering animation in Soulsbourne games but those animations aren't this long and you can at least roll dodge during it happens. Anyway i managed to kill the first boss, it wasn't too much difficult. Comparing to the second boss, it was a peace of cake. Second boss is where i rage quit the game. Okay this is boss hurls at you guided fireballs, like every sorcerer boss from Soulsborne games. The difference is, in Soulborne games those guided magic missiles get destroyed after a while. In this boss fight, there's no way to avoid them. You sprint and get near the boss, you get hit by at least one fireball, hurt animation triggers, by the time the animation ends it gets away from you. Then you get close to it again, it does the ground pounding attack which you cannot avoid as well. The only window you can hit it is the time it teleports itself and you can't even give quarter damage to it by then. When it teleports, same shit all over again. Of course you die before it because it has much more health than you. This is not a difficult boss, this is bad design
Other issues i notices about the game is that there is stamina bar i think but that bar is always filled at the same level and never changes. I think you wanted to implement a stamina system to the game but run out of time before adding it. Throwing your sword is pointless. It gives too little damage and you need to pick up your sword where you threw it and it doesn't make you faster or anything with one sword. In the second boss, the sorcerer goes through the wall sometimes and gets stuck there. Also if you make a Soulslike game and made it this difficult, you should have at least added the estus flask mechanic as well.
These are my general opinions and feedback on your game. This could have been a fantastic soulslike game if it not for the issues i mentioned above. But there is no loss here, you gained very valuble experience as everybody else who participated in this jam, me included. I appreciate the hardwork and time spent to create something. I wish you good luck in your future projects.
