Hey I wasn't expected to see another fps metroidvania here, but that was a pleasant surprise. 

Which engine did you use?

The graphics look cool and the audio works well. I really enjoyed figuring out how to defeat the big spider boss. The remote bomb is great, and the grappling hook was smooth and simple. 

I stopped in the big room with the grapple hooks and the guys shooting guns. One of the gun guys took me out when I was near the top. I'm using just my laptop with the mouse pad, which is a little awkward (no fault of yours). I might come back to play it later. 

Some thoughts:

- Some of the textures look odd? There's some white shapes floating in the air which I think represents a tunnel.  

- I got stuck on the rocks at the beginning when I jumped on them and had to reset.  

- I think the main pistol is a bit useless. I spend all the ammo early on and didn't find any ammo restock. It didn't seem like the pistol was displaying how much ammo it had either. 

- I wonder if those gun skeleton could shoot less frequently / be less accurate? The only way to take them out is the bomb, which requires getting close and taking damage. Maybe upping the movement speed could help a little in those encounters?

Really fun and awesome! 

Not bad

I really liked the soundtrack and graphics in the PS1 style.

And what I would like to note:

1) It is probably worth increasing the walking speed

2) It is worth removing the opportunity to get behind the map on the slope before entering the facility

3) If you die in the water, then after respawn you begin to suffocate
