Fantastic (with great replay value)
A game that tests your reflexes. As you progress and stay awake through more eras, the enemies do more damage. Find your ideal play style with a variety of weapons unlocked in different eras, which are influenced by your choices. Play as a hit and run arsonist by choosing a flame enchantment and watch the enemies burn, or charge into groups of enemies with a lightning enchantment on an AOE weapon, stunning everything and render them helpless. Or you can even stack up damage enchantments and play as a sniper that 1 hits enemies from afar. There are a lot of combinations to try out and see how long you can stay awake (not die). If I were to nitpick, maybe you can make an option to proceed without needing to spend all blood? And perhaps pass over on our choice of weapons when upgrading. For example, I don’t really want higher chances to get a war hammer as heavy weapons regardless of era but you’re forced to get it if that’s the only upgrade left and you have blood points remaining. This makes getting the weapon you want less likely...
