So I finally got round to making a gameplay video after being ill for a week or so: https://www.youtube.com/watch?v=YnHLtkqFSKs
This is obviously for entertainment purposes and not really giving constructive feedback on the game, but I'll do that now.
After playing the game through for the second time it became more apparent to me that the level design is quite plain looking. The texture of the blocks and bricks is great, but overall it's just a bit too samey samey. Being an old temple I'd imagine it to be a lot dirtier, more bits falling apart, rocks crumbling, holes in some of the walls, maybe some vines growing etc. I think more of a tomb raider feel to it would give it a bit more character and realism, it's all very beige currently. If you type "Tomb Raider Temple" into google images, that's the kind of thing I mean. I think it would give it a more creepy atmosphere to it too.
It would be great to add some more natural elements into the game, like earth, fire, wind and water. Having to avoid fire somehow, seeing and hearing moving water, having wind rush by when you're in a more open area, things like that.
Near the beginning when unlocking the entrance, when the big brass 'key' swings down and unlocks part of the temple lock, it does this in silence, when it feels like it should make some sounds whilst doing so. Some creaks and a thud maybe when it goes in the lock hole, something like that.
I think having more things to dodge and avoid would be good. Thinking more Indiana Jones style, like arrows being fired at you, or big blades swinging past. Things to add some more fear of falling off the blocks. Also some inventory items would break it up a bit from just holding the torch the whole time. I'm thinking like maybe a big machete that you need to equip to chop through some rope when you're travelling past to reveal something or release a doorway etc or maybe you have to fill something with water to put weight on a certain block to release something. Maybe you have to shoot something with a bow and arrow. Little challenges or puzzles possibly to add some more thinking and variety to it.
At 4:43 in my right ear it sounds like someone is walking around slightly behind me. Again at 7:44, 8:35 in left ear, 11:55 in left ear & 13:07 in left ear again. You will probably need headphones/earphones on to hear it. These sounds seem very out of place, I can't work out when is triggering them.
At 11:55 you can see the black flashes I mentioned in my previous feedback post. They happen again at 12:28, 12:34, 12:47 and 14:00. I wonder if this just happens for me, or if everyone else experiences this in the narrow corridors.
That's about all I can think of for now. I tried to be as constructively critical as I could, so I hope that helps.
