pretty challenging

It is tough! I made it hard so games would be short and give people's eyes a break and keep them from getting too much of the after-image motion effect.
Despite that, these people at RetroAchievements are impressive with how well they play the game. Better than I can for some of the challenges. https://retroachievements.org/game/24082
