Very good and polished game for a game jam!  It's a shame it's only have 3 votes, people should play it more. Think about a WebGL build maybe?
Keep up the good work! Nice done!

Loved the game and I think it is one of the best from this jam. Almost everything is so good. 

• Firstly the attack animation and camera shake is right on point and feels very nice. The dash also feels good to use. For the jumping I think it needs some improvements: 1. Add coyote time to your jumps 2. Sometimes when pressing jump it wouldn't jump, maybe add some milliseconds when pressing jump button to see if it is near ground, so when it reaches ground it would jump again.

• Moving to enemies design. Enemies are decent, there is variety, but the problem is that, they don't give any value if you kill them. At first I killed some, but then I just skipped all of them to get to the bosses. So maybe adding some reward for killing them would be great.

• Okey bosses design. 2 bosses felt challenging(especially when sacrifized to give them speed),which is great. I think the best boss is that jumping man by far. Having to constantly switch between dodging and attacking is what makes bosses great. So other two I didn't enjoy very much, because you wait and dodge until they come down and after a few seconds they go up again. So yeah making more bosses like that jumping man boss would be awesome. And one more point, that rectangular boss, in the right, on the second run got very borring, when I sacrifised for 2 bosses aggresivnes and 2 for projectile speed, it would stay up for about 5 to 8 seconds and then come down for 2 sec. So it took way too long to kill it.
• And finally the sacrifise mechanic is very good and I really enjoyed it, don't have anything else to add.

So yeah loved the game, would love to see more.
