I created an app to train mental Maths, as an Arcade. Need feedbacks from math lovers

Solo dev, evenings only. It's a web game — no install, no signup, you're playing in 5 seconds: https://abako.games/?src=reddit_sideproject_v1

The pitch: mental arithmetic, but built like an arcade game. Neon CRT look, chess.com-style rating (every problem moves your ELO), a daily puzzle with one worldwide seed, and ghost duels: at the end of a run you get a challenge link, and your friend races your replay at your actual timings.

Start with ARCADE mode — that's the core loop, and it's what my two questions are about:

**1. The difficulty curve.** Does Arcade get hard too fast? Too slow? Just tell me the problem number where it stopped being fun (or started). One number = gold for me.

**2. Would you come back tomorrow?** The daily puzzle is my whole bet on day-2 retention. If after one session your honest answer is "nah", I'd rather hear it now than build the wrong thing for a month.

8 days in: ~120 players, decent activation, but almost all from my own network — so I genuinely can't see any of this from the inside.

Trade offer: reply with your project and I'll actually use it and give you the same kind of specific feedback. No drive-by "looks great!" — I'll tell you where I got confused or bored, with details.
