MetalHell is a clockworkpunk themed Bullet hell, “danmaku”, game. Fight against mechanical insects from hell – in space!
The player dies of one hit. Enemies drop tech-powerups (increases canon strength), more bombs. Timebombs slow downs time for everything in area, use either defensivly to slow down incomming bullets of slow down boss. Gravity bomb sucks in enemy bullets and uses them against them. Killing enemies increases your score multiplier.
The engine is custom made using C++ and SFML. It is highly customizeable and one can create own levels, just place them in /levels/ and append to /levels/levels.txt. One can even define own enemies and AI.
