Unless the author would expect it, I usually don't compare individual games on MFGG to other games, much less my own games.

However, when I played Bullet Bill Attack, I couldn't help but think of a part in one of my old games, Super Mario Fury, which for quality reasons, I have yet to post on MFGG.

That particular part was almost identical gameplay-wise to this game; nothing but lots of redundant bullet patterns to weave through. Pretty bland by itself.

However, in Mario Fury, this mechanic was a small part of the greater gameplay experience; the bullets were one of many attacks by a boss, and simply figuring how to dodge the bullets was not enough. You had to beat an evolving boss, making for a more interesting challenge than simply increasing bullet speed.

While Bullet Bill is intuitive and plays correctly, i.e. no noticeable glitches, surviving 100 VERY long seconds is a battle of attrition more than skill.

The gameplay is just too simple, repetitive, and thereby a waste of the player's time.
