Steam review snapshots
The bosses in particular can be absolute bastards and after the first few always took me at least a few tries.I get the immersion, but I doubt anyone will play this game on an NES controller nowadays.There are some things to make it easier for players: you can buy quick-heal items with money, and there is exp system…Bosses can seem tricky at first but with some exploration to gear up and patience to approach them with intent they turn…Why it fits
Check it if you want action, adventure filtered by single-player.
