Hi!
You did an admirable job of preparing a project for Steam Next Fest. It took courage to execute and I'm glad that you learnt a lot of stuff from it.
Reading this post, I think you're still missing a critical learning point though. I have been participating in your monthly game jam for several months and been playing Hungry For Loot. Over time, I saw the game has always been progressing toward a good game. However, the one thing that the game lack is the "appeal" factor. It is fine if the project is still under gameplay development. I was under the impression that you will some time in the future implement the appeal factors that make people want to play an RPG in the first place. These include theme, story, presentation, and music.
In the current state, Hungry for Loot suffers from a mismatch between theme, gameplay and presentation. Playing as slimes in a slime-world invaded by humans is quite a unique theme to be explored. However, all the gameplay and presentation still point toward playing as generic human characters. Flipping around the players and enemy characters would solve the mismatch, but the game will be another generic RPG that is already flooding the video game market.
Hungry for Loot with its current theme has potential, but it is still very premature. I honestly think it is not ready for market yet if that's what you're targeting. The thematic/gameplay/presentation mismatch is the biggest issue to be tackled first.
I hope I didn't sound too harsh in my opinions, I am quite interested in finding out what kind of unique game experience that will come out by playing as slimes. That's why I was interested in following the project in the first place.
I hope that you came out from this Next Fest experience as an overall better game developer. Let's both make better games! Cheers!
