I tried making a game using qwen3.8-flash, which I brought back with a solo spark.
I switched to a tool called dgpp and it showed over 40 tokens on the benchmark, so I had high expectations.
I'm going to make a game with prompts. It will be a vampire survival game, so I did some research and based on that, I created a concept design. After further research, I supplemented the missing parts and calculated the workload to divide it into phases. The work involves summoning sub-agents like agents and forming a team consisting of a team leader, coder, and reviewer. The team leader reviews the phase-based design and tells the coder and reviewer what needs to be done in this phase. Once the phase is complete, they need to record what was done in this phase and what remains to be done on the design page with phases. Then, the context of the development team should be reset and initialized, and they should read the design page and continue the phases until completion.
This resulted in 5 phases after research and design, followed by a full game review...

It took about 17 hours.
Fortunately, it didn't crash in the middle and worked well. However, it was slower than I expected.
I'm finishing it up and making some minor adjustments.
Except for balance issues, experience points not increasing, and skills not being applied, it's pretty good. It even has background music. I liked that I was able to create a complete game at once.
Since it's a web version, it's only this much. If I had to make it native using another language, it would have taken much longer.
Using APIs is good for mental health, but there's also the fun of wondering "Can I really do this locally?"
