I was able to improve the current five cognitive tests which is the important part of this project, each test has a detailed indroduction upon hovering over it so u can choose swiftly .I was focused on the dialing of the typing test mechanics so that keystrokes feel smooth and responsive, complete with live wpm and accuracy tracking right over an endless stream of text. I spent much time squashing bugs across the visual memory and aim tests, cleaning up performance leaks, and polishing the overall flow of each test especially the wpm test,I overhauled the event listeners and timer logic to eliminate performance leaks, fixed layout shift issues during high-speed clicks, and polished the overall visual flow between transitions Along the way, I refined the test flow with clearer instructions, countdowns, better feedback, and more consistent scoring across each challenge. Paid alot of attention to the smaller details from making the reaction test more precise to keeping the different tests feeling responsive and fair across different setups which makes Cognitive Arena feels less like a collection of mini games but more like a complete cognitive approximated testing experience . There are still plenty of things I could keep tweaking and later on i am planning to update this, but I think it’s finally at a point where it’s ready to be shared before upcoming cool updates like adding more tests or a progression chart to maoe it more challenging but right now its enough as a quick test of your cognitive skills
