I don't think it's a game with all the confidence it could have, and the one thing that points that up is the music, boring to hear after a while. At the same time, for a game that explores its possibilities but doesn't dig seriously in them, I think it fits, and that's not a compliment.
Take 'New Super Hook Girl' for example, a freeware game, shorter than Elechead, but with fundamental differences, such as:
- Showing the most fundamental mechanics in a very short first level.
- Having very diverse levels (only 5) where even if the mechanics are the same, don't feel the same.
- And the most painful one: it doesn't drag on.

ElecHead doesn't trust in itself enough, to the point where it chooses the path of showing but not going most of the time. The difficulty of the puzzle solutions feels adequate, but that happens very late, when the way of solving them is A) unique; or B) open. In comparison, everything before some of the last rooms is just rudimentary.

Sometimes I think that avoiding to put stuff related to humanity in videogames can cause coldness. Even the few instructions that are given to the player feel like it's sent via machine from an uninterested authority.
It may be useful to work in a videogame that way, if that guarantees concentration and continued results, yeah. But if a game is about going from A to B, repeatedly, it needs more drama.

Enjoyable, short little platforming puzzler with very simple mechanics used in some interesting ways. Some levels were definitely challenging but not because precision was needed. Once we figured it out and had the light bulb moment (heh), we immediately felt like we should've noticed the solution sooner. The way the game's two potential endings wrap up are well worth seeking out on your own without looking up spoilers. Leaves you with a little something to chew on that you don't normally get in a game like this that seemingly has no narrative whatsoever attached to it.
