Hi! Thanks for your interest in Vowel Stack and for taking the time to ask these questions. Here are the details.
1. Gameplay and functionality
The main features are implemented and working, including the game modes, power-ups, daily challenges, customisation and leaderboards. I haven't discovered any bugs so far, although I can't guarantee that no undiscovered bugs exist.
You're welcome to download and test the game from my itch.io page before making a decision.
2. English progression (A1–C2)
The A1–C2 levels are used for Cubey's character progression rather than as a structured English-learning system. As players earn XP and unlock more levels, Cubey unlocks additional dialogue, progressing through the levels. The game doesn't currently assess the player's actual English proficiency or provide a structured vocabulary-learning programme.
3. Backend and running costs
The game uses SilentWolf, a service designed for Godot, to handle online leaderboards and player data. Player data is saved both locally and in the cloud, so the game supports online and offline play. The online leaderboard requires an internet connection.
I haven't incurred any known recurring backend costs. However, the buyer would need to check SilentWolf's current pricing, service availability and terms before relying on it long-term.
4. Assets and licensing
Most of the graphics are AI-generated, while some are from Godot's own resources. The audio and fonts/resources were sourced from Pixabay and other royalty-free platforms. The font files are already included in the game's project folder. I selected these assets for commercial use, but any third-party assets remain subject to their respective licence terms. I would recommend reviewing the relevant licences as part of the acquisition.
SilentWolf is the only third-party plugin I have identified in the project. You would need to use your own SilentWolf account and arrange your own access to its services.
5. Project handover and ownership
The game is currently available on itch.io, Uptodown and APKPure. If we proceed with the sale, I will remove my own listings where possible and remove my name from the game before the handover.
For the $150 asking price, you would receive the complete editable Godot project, including the source code, scenes, scripts, project settings and game assets. I am offering to transfer all the rights I own that can legally be transferred, subject to any applicable third-party licences and terms.
The game would be sold as it currently exists. You can test it before the sale, and if you discover a reproducible bug in the existing game during that testing period, I will fix it before completing the sale. The price does not include new features, additional educational content, future development or support after the sale.
Payment
My preferred payment method is cryptocurrency, particularly USDT or USDC. You can send the agreed amount directly to my wallet using a mutually agreed network. We would confirm the network and wallet details carefully before making the payment.
Unfortunately, I can't accept PayPal or Wise because of payment-service availability restrictions in my country.
If paying with cryptocurrency isn't convenient for you, I also have a Getly store, which may offer a checkout option suitable for you, including card or crypto payments. We would need to confirm the available payment method and the applicable terms before proceeding.
Agreement and next steps
If you decide to purchase the game, we can sign a short written agreement covering the $150 price, the complete project handover, the transfer of the rights I own, third-party asset and service limitations, and the timing of the transfer. The transfer would take effect once the full payment is confirmed, in accordance with the agreement.
Once we've agreed on the details, we can arrange the testing, payment and handover.
Let me know what you think and which payment method would work best for you.
