Demo is out! Yes! Congratulations on your first Steam demo :D

I played a little and am impressed with the amount of work you've put into it.
(I don't really realize how much work I did myself. Seeing how the assets are used and how the game plays, it all feels new to me).

The excellent atmosphere is the first thing that struck me. The voice acting is fantastic and helps the game stand out among similar RPG Maker games, I think. I really enjoyed the first exploration segment. Tension rose gradually, which is great. Loved the chasing segment and how real it felt. You really did a great job with the art direction: how the scenes play out, how the Lurker moves, the minions' lines, etc.
I appreciate that despite the horror/tension/dark themes, you added a generous amount of humor here and there. I had a good chuckle listening to the ZEAL cola ad on TV :)

I fought a couple of times before I stopped playing for the day and added the Arena-Bot to my party.
I have only one bug to report but it's an important one: Before I stopped, I noticed that I could no longer open the Ring Menu by pressing Esc. Maybe the function was disabled at some point? Unfortunately, I did't notice when.

So far, I'm having a lot of fun. I'll play more and share my comments again :)

Thanks for the tip. I fixed the Ring Menu by listening to the first computer that plays an audio file.
I've enjoyed fighting more enemies and really like to figure out optimal attack combinations between R3-M1 and the Bot. I like how upgrades are available fairly often and you don't have to grind for them.

I have 2 more bugs to report:

-While I was listening to that audio file in that room, one of Sagrim's dialogues came up, asking me what I thought of the minions. The emotion icons appeared and stayed on screen even after I left the room. I could answer and continue the conversation even without being in Sagrim's room.
I did meet him earlier but didn't get that conversation until now.

-I grabbed this loot box after the battle here, and this error message came up. Now it comes up every 4 seconds and pauses the game until I press Enter. What is this movie supposed to be? I searched through the movies folder but no file seems to bear that name.

Yes, combat is really fun so far! Each new enemy is interesting to learn about and makes the first battle against them suspenseful. Once you figure out the best attacks and combinations to use against them, it becomes quite satisfying to defeat them quickly.

I have a few suggestions and more bugs to report below:

I think there are enough states for now, but I would like if there were more Reactions so that every state has 2 or 3 possible reactions.

It would be nice if Toxic Cloud and Soaked had a standalone effect to make them more relevant outside of combinations. For instance, Toxic Cloud could reduce Hit rate and Soaked could... I don't know. Maybe make the target roll the minimum damage? Both states only last 2 turns so these effects wouldn't be overpowered.

In order to make Experience more relevant:
It would be nice if we could upgrade the chances of inflicting Disoriented and Exposed for the Light Attack, Particle Blast and Lunge. Maybe by +10% per upgrade level? That way we could feel the satisfaction of unleashing Reactions more often.

Also if we could learn and upgrade passive skills that cost a lot of Exp, for instance:
-FDM rises when taking damage (+1 per upgrade level)
-A slight resistance to each State (+10% per upgrade level)
-A higher chance to get more/better loot after battle
-A chance to get more Exp after battle

Here's my bug report:

-The missing movie file bug didn't appear after I launched the game again today.

-Double TP: replace TP with FDM in the name and description.

-Disoriented description: replace Standard Attack with Light Attack.

-Aqua-blast state info: capital B to blast.

-The Standby actions do not increase FDM by 3.

-Gas Cloud and Toxic Cloud, both terms are used for states and abilities' descriptions. Make sure it's the right term everywhere.

-Bile Armor under Enemy states and Bile Protection under Health states, are they the same? They use the same icon, which might be confusing.

-The abilities' Current and Upgrade information on the KARN machine don't always reflect the full or true information, for instance Shockstrike costs 35 FDM but is said to cost 30 on the KARN machine, and Burning Cleave's description does not mention the explosion.

-Cool bug: I modified the bot to have the gunner version. Later, I reverted to the standard version and there were two arena-bot sprites in battle with me (one gunner and one standard). Their FDM numbers were superposed (I can tell because they're not aligned) but they seem to have a single gauge even though they both have their own numbers for abilities. They can both act in battle. R3-M1's "ready" sound plays when the first (gunner) bot's action is selected and when I cancel the selection.
I modified my bot to the gunner version again and the standard one was gone. Only the gunner bot remained in battle. But I can repeat the bug anytime.

Any news about the lighting script and if it could be applied to battle maps eventually? If not, I was thinking that we could modify each battle map in Photoshop. The sprites wouldn't be affected / would have to be affected using another method, but that could be a start.

That's it for today :)
I'm about to go fight the armored Brute. Lookin' forward to it!
