Like the idea, both the movement and control feel perfect, personal preference, I thought the game was way too hard, the highest skulls I got was 2 it would benefit from some kind of indicator when one gets into a specific range. 

This game has a cool vibe!

I fired wildly but I wasn't sure if I had hit or not, it seemed like there were still a lot of enemies chasing me.

The visual is very fantastic! It made me wonder what techniques you used.

But honestly, I don't really get into your theme interpretation.

Really neat game, I liked the vibes, but the controls just felt way too unresponsive to play and you often seem to just die out of nowhere due to the lack of any indicators / what seems like enemies can spawn on you if you're at the spawner.

A great survival mode arena shooter where the enemies just keep coming! Smooth controls and solid gameplay. The music is eerie and fitting to the setting and aesthetic of the game. Great graphics, exciting gameplay, and all-round just a fun game. Nicely done!

I think I killed the heretic lol.

Great stuff increadibly hard I think I found the way to kill it all the time but it requires a sudden change of direction but often I got hit by the sacreds.

Great idea and awesome 1 bit entry

Simple but very atmospheric. The interval before the arrival of the skulls is eerie and well executed. Perhaps it is a little too difficult for my taste, but I will keep playing it to practise!

Oh wow, the ambience of this game. You guys did a great job!

Cool game

One of my favs of the jam. Looks really beautiful and very atmospheric. One of the few games that I wanted to play again and again. Excellent job!

The ambience really got me, I cant seem to get past 30ish seconds though. Fun game! Loved the SFX and how creepy it all sounded. Falling into the white did trigger my thalassophobia a bit XD

This was really fun! For some reason I thought I was a stationary turret the first few rounds. Once I figure out that I can move and shotgun blast I was able to to get up to 1:05. The heretic was great foil to the strafing strategy and I was forced go straight back in order to kill them. Awesome job!

Very atmospheric.

The laughing sound of the skulls is very creepy in the best way.

My longest survival time was only 0:33:42 as the heretic always gets me.

Really nice submission.

Very fun, very challenging. Definitely scratches my competitive itch to continuously replay and get better scores.

Nice game! The 3D 1-bit art style is done very well. The ambient music & SFX are great too. The game is a bit too difficult and doesn't match the theme.

Well the game is really hard, could do a little difficulty settings, maybe also a crosshair, but that's the only negative thing I have about it. The art is actually amazing! I adore the effect of light blending in with the dark, and the trail effect of the player was a great choice as it looks really good while moving. The SFX and atmosphere sound are also really fitting. Overall, that's awesome work!

These skulls kicked my ass!
I played a little longer than I care to admit before realizing I could move. That improved my score quite a bit. 
I think it's all very smooth, and I think that using your survival time as the score makes a lot of sense.
I think the rest of the comments below kinda cover everything else so I'll just say I enjoyed this, it spooked me, and I confirmed suck :D

This is a great submission! I have a lot of respect for developers who choose to do a 3D game for these short jams even if it's relatively simple. I always do 2D for jams since there's so much less to worry about. It's also an enjoyable experience although I agree with a few criticisms made by evigouroux and SoulsTogetherX. Mainly I wish it was easier to contend with the enemies since they spawn frequently. Could just be that I suck though. Despite that, I think you did an overall good job!

Really cool! Nice work!
