I thought this game was amazing. I was really just amazed at what they did with the engine considering that it's rpgmaker. I was just blown away.

The story was alright, kinda what I've seen done before from what I'm already seeing. Music was good. Gameplay was pretty good.

Personally, I liked how the game was easy. There were parts where I was stuck but once I figured out what to do it got easier. The whole unlimited tries was great.

The only cons I would say is that there was a black bar that appeared when you go back outside. And, I got stuck in a wall when leaving a room. Luckily the phone was right under me so I teleported to floor 1.

Hey Wallace, thanks for the feedback! I'm working hard to fix up some of the issues you mentionned. Glad you enjoyed your playthrough!

Hello again, coming back to this comment because it stuck with me. 

As someone who wants to be talented at (amongst other things) storywriting, it's actually really encouraging to hear that the story was "meh", but that you still enjoyed your overall experience. It tells me the project itself is good & that my efforts aren't wasted, even if there is still a lot to fix.

Weird out of place statement, I know, but felt it needed mentionning. 

Thanks again!

Np! I didn't think the story was "meh." I thought it was good. I just felt like I knew where it was going and that's ok. I would still like to play the final game. :-]

I really liked the game but I had some issues: When I try to question Ivan he switches into Lloyd and I don't get his actual testimony. The game stops when I talk to Julia the pink robot.  Nothing happens when I present facts to characters with 0% like Margaret. Detective gets stuck from time to time


Oups, my bad. I forgot to lockout the rest of the game. (Anything after Yvon should be considered unfinished content.) These aren't bugs as much as they are unfinished game elements. I'll be posting a new version fixing these soon. Thank you for playing!~ I hope you enjoyed it.


I did! I really liked the game :)

Looks rlly cool and im gald you made it for cheap comuters to play but when i was playing i was walking the halls rigt after i enterd the mansion i went through the wall and got stuck and couldnt move at " Floor two main hall i went to the right side."

Thank you for playing! I'm glad you enjoyed it. I'm currently looking into this issue. Should be fixed in the next build 


Floor 3 upper hall, if you leave the old door (nasha room), Beatris disappears

Thanks for the report, I'll look into it.






my world this looks so beautiful, and that's not just because teal is my favorite color

Thank you! I'm glad you enjoyed "Lockheart Teal" :P


real nice game, I like how the final guy wasn't convinced by your act

Im in love with your game!

However minor bug, sometimes when I enter a room, il get stuck in a pervious hallway's wall, able to move direction but not walk anywhere.

Another minor bug I've came across; when I changed the sound, then went to press x , and error screen came up, 

Glad you enjoyed it! The hallway bug has already been fixed in the next version. I'll look into the volume bug, this is the first time I hear of this.  Thank you for the bug reports!

First things first, OMG! I just found this game and I played through it and I LOVE IT! I really loved all the new mechanics added to the base RPGMaker. All the puzzles and traits are really clean and I never found myself stuck on any one problem. The rooms were all unique enough that I never felt lost, either. The only problems I had was the warping through rooms. I found myself stuck on the other side of the phone on the first floor and a couple blocks too up from another room. All the characters I felt too felt vibrant and colorful, not just because of the great use of color, and that ending! It kept me on the edge of my seat for the whole trip! I can't wait to follow the development of this game! (Also the art is amazing! I need to emphasize what a great moment [insert spoilers here] was!)


First off, I want to thank you for your enthusiasm. I take it to heart. I'll jot down the issues with the phone & try to patch them soon. I'm curious to know which spoiler you're talking about. Do you mean the later scene with Yvon? Thanks again for playing!

I got a minor bug. In the Doc's Ward in the room just above the morgue area theres a spot of blood. Investigating it just gives me the message "The Chair was Cleaned"

Thanks for reporting the bug! We're on it.


I remember trying this out a while back, I've been meaning to come back to it.

Just played through 2.1 and I absolutely loved it, great job! Can't wait to see more!

Thank you for your kind words! I'm doing my best to get the game at Alpha & Beta state quickly. For feedback, do you mind telling me what you enjoy (or don't) about the game? Thank again!


Hi! Just chanced upon your page again and saw that I must have forgotten to respond to you! Sorry about that!

Obviously it's been a while since I played now, so I can't recall any specific criticisms. I remember I encountered a bad teleport at some point which softlocked the game, but upon re-loading it didn't happen. Can't remember where abouts that happened though, sorry.

I pretty much liked everything about the game though! Enjoyed the writing, art style is great, music is fantastic. I found all the characters interesting and mostly I was just disappointed when I reached the end of the demo!

How is this project coming along anyway? And what are you plans for it in the future? 

I'm glad to hear! I'm tweaking the mechanics of the game at the moment. Once that's done, I'll be writing and revising the plot for the rest of 2018. We'll see after that. Cheers!



I had a question.
What software did you build with this game?
