it’s an arcade-style 2d side-scrolling adventure that resembles old amiga days of Shadow of the beast. – running is faster down the slopes, slower up the slopes
– you can shop when close to the old man (to shop, crouch)
– you can drink potions to regain a portion of health
– you need keys to open chests
– when shooting, timing is the key
– almost each enemy regenerates health over time.
– killing multiple enemies in a short time makes you enraged for a short time: you shoot faster and regenerate some health
– you gain experience with each kill; you gain better weapon with a levelup.
