Toshi Tensou Keikaku: Eternal City (PCE/TG16, 1991) - WIP

Some ability gating via the back booster (lets you fly around or dash forward while on the ground)
Some backtracking through previously visited areas to get to new ones? (seems mostly linear in structure though)
Password save (kinda long, get them at "save" points)
No map? (pretty repetitive backgrounds and large maze areas with various dead ends)
Stamina/energy meter-based weapons
Most weapons and other upgrades seem placed in the open

Playthrough - Review
