Hi there! First of all, congratulations on releasing your demo! It is a big step!
I was checking the "unanswered posts" and saw that a lot of work obviously got into this.
Everyone knows Solo game dev is one of the hardest things ever because you have to do EVERYTHING. You're doing a lot of things right so I will only focus on a few points that I noticed and here's what I would do if I were you:
- The teaser is way too long. It needs to show key elements of your gameplay. What makes its uniqueness. Your selling points need to be things that are original and unique. I saw "Kill your opponents", "An action roguelite where you can break bones", these sound way too generic. Also, the text at the end says "Sign it now". I'm not sure if you meant "Whishlist now" or "Try it now".
- I unfortunately couldn't try the demo because my gamepad is somewhere in a lost box on a shelf, and I was sad to see there was no keys mapping for keyboards. For me that's a big big thing you need to implement. The possibility for players to use both.
- Third and last point. Screen readability. Your environment backgrounds and your characters are blending way too much. They are in the same color tones which makes it a little hard to see what's happening on the screen. Screen shake and flashes add a little dynamism but overall readability is very important. Perhaps make the environment darker. I'm not sure if that would require a lot of work to change that but I believe it's quite important.
Don't hesitate to up this post if you decide to include keyboard control to your demo, I'd love to try it.
Good luck ! You've already done a lot.
