1000 Amps is an exploration game, structured similarly to a metroidvania game but with unique mechanics and no combat except the final boss. The game world is split up into various rooms which you are tasked with restoring power to by activating all the energy node blocks in each one. It sounds easy, but your character's jump height is tied to the % of power restored to the current room, and each room resets if you don't complete it before moving to another.
As you progress through the game you acquire new new abilities which let you deal with new obstacles the game throws in your way in metroidvania fashion. Some rooms require quick reflexes and timing, while others just require some thinking. Overall I found the puzzles well designed, though a few can be frustrating. The biggest weakness though is that there are quick a few lengthy one-way passages, and if you miss completing a room in those areas, it takes a while to get back there.
It's a simple game, but a good one. The difficulty is higher than the appearance would suggest however.
