Thoughts as I play.
- I don't think that's how breathing works.
- The camera feels immediately off. It's very sensitive and very floaty, and moving the cursor from one side of the screen to the other causes this awful vertical "bump" that's a bit nauseating. I'm not sure what the best way to describe this behavior is, but you'll see it if you move the camera left and right with significant speed.
- I killed some guys, combat feels alright but pretty slow. The player and most of the enemies move at a slug's pace.
- A little too much screen shake in my opinion, but it's nothing debilitating. Definitely make it configurable.
- Blood effects are cool, but the fact the splats are fairly spread out and don't disappear with time makes them look more like autumn leaves than blood splatters. Maybe that's just me.
- The enemy sightline visualization is neat, I wonder how relevant that will be.
- The blue crystals sometimes spawn out of bounds. I'm not sure what they do when I pick them up.
- The noisy background muddies up the visual clarity a lot, it's not easy to tell what's the level and what's the background at a quick glance. Maybe just flatten the values of the background in a particular direction instead of having a mix, i.e. make the background really dark or really bright.
- The portal sprite looks horrendous with that wobble, we're beyond mixels at this point.
- Not sure what extracting is, I'll continue and do that next level.
- The cursor reloading graphic puzzles me. There's a rising orange bar and a blue line: you'd think the blue bar represents the end of the reload, but no. The orange bar extends past the blue line. Is this an active reload minigame or did the widget break?
- The room barriers during combat are a little lacking, they're not immediately obvious. I backed up into one that appeared right behind me without me noticing and got swarmed.
- I started a new run, but my health is still 0. I am invincible now, in fact. I refreshed the page to fix it.
- Found a purple chest that I can't open. Okie.
- Extracted after a level. I have a few crystals and runes and whatnot. I can't seem to do anything with them through the menus, so I assume you haven't implemented this stuff yet.
I'll stop here. I'm not sure what this game is after playing it, I can only surmise it's some kind of roguelite where you pick up stuff to build spells? I'm not sure. It could be fun, but it isn't right now. I would work on it more until you can call it a proper proof of concept, then evaluate from there.
