Bikkuriman World（僅卡匣）

Those limited health bars force some truly tense moment-to-moment decisions, and the colorful graphics really pop on a CRT. The risk of spending it all in the shop just for one upgrade feels perfectly balanced.

The shop mechanic is such a clever risk-reward twist—I found myself gambling my last few health points just to afford a better power-up, and it made every run feel tense in the best way. The colorful sprites pop nicely on my CRT, and the old-school difficulty brings back that pure NES-era thrill.

The limited health system forces you to play smart, especially in the later stages where every hit matters. The shop mechanic adds a welcome risk-reward element that keeps each run tense.
