Ah, the very prolific Rebel 357, trying something different eh?
I truly hope the sex scenes have evolved past the menu system.
Lets' give this a shot!

Do you mean how most of my games created with Ren'py are usually menu heavy? I have gotten tired of it and felt like I need to explore past Ren'py.

I'm already thinking of an update for this one. Majority of the content and groundwork has been completed with the prototype. There is even a short ending that was included with it. This game project won't be large. I have to stick to making them small, just don't have the motivation for large and complex game projects anymore.

I do plan for a bit more sex content. I'm also going to see what I can do about expanding or adding some more short scenes here and there. Another plan is to add more stuff to explore, fix possible bugs and improve what I can from the game.

I don't consider this project 100% complete until the game engine adds a basic and important feature of allowing player to adjust SFX and BGM volume.

This is from the original project idea back in 2023, but does anyone like the female love interest Petra with her alternative hair style with her bangs covering her eyes? I'm thinking of making some content with her having her bangs or some kind of alternative fashion for content.

Update 1: Some changes have being made for the next update. I have a few things did so far but I feel like some balance is needed for some stuff like the healing for Petra via "healing Meditation". Likely will add a few more stones to break down in the maps outside so that your not constantly meditating for them to replenish. The key item Pocket Camera can be used for some temporarily changed game camera positions.

Version 0.10 *WIP no ETA yet!

• Updated Game Engine to 3.2.8
• Adjusted Witchy Shoes to close item menu after use
• Adjusted item “Treo 650” to close menu after use
• Witch/Petra is now stationary in her room instead of randomly walking around
• Fixed Petra Talk on last dialogue variety that is based on Affection
• Changed Hint 12 description
• Added lighting effects for the 2 floor lamps in Witch’s/Petra’s bedroom
• Added Reset option for floor lamp in MC’s bedroom
• Fixed Object gap for Stereo sprite in Living Room
• Fixed Object gap for PC in MC’s Bedroom
• Added key item “Pocket Camera” for adjusting camera angles. So far there's a FPS camera angle, zoom in 1, zoom in 2, zoom in 3, zoom out, camera angle 1 added.
• Added a new gardening action to raise the male MC’s psychic defense by 1
• Increased healing amount for Witch/Petra when spending 1 single crystal on healing meditation

Update 2: Since the game takes place in 2005. I worked on some bonus content for Petra such as alternative hair color, hair style and fashion. This one in particular is Petra in emo fashion complete with some piercings. I have created several character cards for her with alterations.





Update 3: An update is close by. I didn't think I would have another within a months time due to wanting to wait on reports of stuff being broken, buggy or game balancing. I've added a bit more content and a bit of polish. There is an object/OBJ where you can change some UI option such as font type, font size, font color and window style. It's a work in progress but I've also done a bit of translation using AI. As much as people love to blindly hate on AI, it has it's uses.


Update: Version 0.40 is now here. With even more content than I thought I would be added. I've added 2 new endings. As for the game, I'm not sure what else to add apart from more translations. I don't consider the game complete until the game engine adds a setting function for the player to change the SFX and BGM volume. That reason is the same for the previous project "The Depressed Dude Isekai".

Updated Aug 28,2026: The assets provided in the link are for use with a modified Koikatsu/Chara Studio. Use the Better Repack version and have the mods and plugins installed via the KKManager. The KKS assets includes:

• Studio Scenes *Not all, too many quickly take up space and results in a very large file size for this pack
• Character Clothing
• Character Cards - Female
• Character Cards - Male

Why is it when i launch the game, it just stays on a loading screen and plays a song by three days grace?

This is the first I've heard of that happening. Also when people report bugs they should include as much detail as possible.
like platform, game version, game download link, etc.
So this loading screen remains stuck indefinitely? I know when I preview test the game it takes a few seconds to load, but that's for the test preview and for the current version of RPM that I'm using.

Ah I had to wait a bit longer I see. Nice music by the way. Loved these songs growing up lol

Every game project I worked on, I place importance on the soundtracks too. It often takes days of research, often to find songs that I don't even know, finding songs that will fit the game project, further research on the music genre and songs that are selected. Finding those hidden gems and deep cuts has been worth the effort.
I know my music tastes is not liked by everyone, so that's also a gamble. I have noted in the documents for the BGM list, that some songs were rejected. I had some doubts about making more songs from the metal subgenres to make it in the game.

I'm already working on a similar project to this one. In order to learn a new game engine, one that uses GDevelop this time. As for that soundtrack, nothing after 2005, since that's the time setting for the game. TCW:A has a few songs that are actually after 2005.
