    Hello, we have a game concept. It's only half-ready now. We need to make changes to this concept and change some logic. Let's divide the work into several parts. The first task is below: Description: The game consists in trying to beat the opponent, and in case of a successful beat (the opponent does not guess the direction of your hit), you move on to the next stage. After 9 successful stages, you play against the goalkeeper, if you win, you win the jackpot. The game you can check here - Now: - The first nine (successful) steps you play against the player as if punching the ball through him. The problem is that it's not logical, and it's hard to draw the player's beat. We need: - Two players on your team will be behind the opponent (to the right and left). ...

    We developed a game-engine based talking avatars for a cinematic multi characters project. I was checking the potentials of doing a light version online and saw potentials in an old JS based platform (will share links below and more useful content once we discuss the project with you). So, we want to try that in a small "project" that requires no sophisticated stuff before making decisions. If the stuff below were done 6 years ago, I imagine it is more doable now. Follow the links to make the point clear: Here is a talking avatar with saved wav files you can click to test (open in chrome, and give it time to load for all the links below): Now, instead of saved wave files, we want to be able to edit that sample, as an example, so we can post wave files to it (maybe via a JS a...
