When I first saw the game, I honestly thought it was going to be one of those generic element-combining games, but turning that concept into a roguelike was an absolutely amazing idea.
The core concept is really fun and I don’t have much to complain about. I’m not sure how the full game would play out since the demo ended after defeating the first boss, but it definitely left me wanting to see more.
The main thing that confused me at first was how the elements actually worked. There are a lot of different combinations, but it wasn’t immediately clear what each element was useful for or why I should combine certain ones. It also took me a while to realize that I actually had to extract the elements, so maybe that part could be explained a little better early on.
One thing that could be really interesting in the future would be making the world itself react to your build. For example, using too much fire throughout a run could slowly make rooms hotter or more unstable, while relying heavily on ice could start freezing parts of the environment. Certain enemies, rooms or even later bosses could then be affected by what you did earlier in the run.
Another cool idea could be unstable combinations: extremely powerful element mixes that also come with some kind of downside or unpredictable effect, making the player decide if the risk is worth it.
It could also be interesting to have occasional situations where you temporarily lose access to one of your main elements, forcing you to improvise instead of relying on the same build for the entire run.
Overall, the roguelike approach makes the element system feel way more interesting than I expected, and the game has a lot of potential.
