This is one of those rare situations where giving best overall a rating is misleading. One of the best boughts from Nintendo 3ds eshop I have done, was a game called "Ascent of Kings". Funny thing was that despite that being one of the games I have enjoyed most having bought, and which had excellent price value (it was maybe 3 euros as normal price), it had been rated only 2 starts out of 5, and when I thought about it, indeed, I would give it 2 stars too, since it simply doesnt earn more than that, despite that I fully recommend people to buy it, which is normally not the case with 2 star games.
Your game is one which I again rate only 2 stars (In Best Ocverall), since there simply isnt enough to justify more, but this is one of those games that I really liked playing for the little it had.
I would have very much liked tehre to be more levels, since the idea of the game of using mouse to move the light, and not actually needing to get that close to the enemies, seemed like a mechanism that gave all kinds of interesting possibilities, but now they are not explored much, also, just like HanClinto pointed out, this could be two player Co-op too, and actually, specifically parent-children co-op game.
For when my daughter was something like 4 years old, we pplayed Donkey Kong on Wii U, and it was very good Children-parent co-op game, as long as child doesnt figure out that he can actually jump out of Dokey Kongs back.
For point is that when you start the game, or die, it always starts with Diddy kong or the girl version being on Donkey Kongs back. And then the one on back was able to throw bananas all around, by ohter words, hekped donkey kong, without affecting movement in any way, only helped, didnt hinder, so me, the dad, was able to concentrate on a typically Donkey Kong difficult platformer, while my daughter at same tijme was throwing bananas around helping me.
I can see similar potential here, as in parent going around the platformer, and then kid keeps frying those enemies with that light.
And even if you would keep this as one player, like it is now meant to be, I assume, it is still an interesting mechanic to give new kinds of possibilities, specifically because you dont necessarily have to get everywhere, but you only need to get the enemy visible on the screen.
Which reminds me, there is actually one problem with the game, for I started by making the game fullscreen, but when you make it fullscreen, instead of aking things larger, it actually increases the amount visible on the screen, which made this game bit too easy, as almost every enemy (i think there was perhaps only 1 or 2 enemies notinstantly seeable), meaning, all you had to do was move the light. I first wondered what was the poin in having the platforming at all, until I tried second try to make sure it really was everything there was after it said "You win", since first I thought the game just froze, but when I started second time, I this time realised that much less of the screen was visible, when I handt made it fullscreen, making the game more interesting and better.
But the little it had worked nice etc. although it felt more like a taste rather than actually something complete, since after having dfinished the game, I felt hungry for the second level.
Unfortunately rating will be bit on the low side, since it just doesnt have what to give more, but the little there was, was actualy very good. Just Couple more levels would have easily upgraded star rating with one more already.
