Sleep Attack

Well made game but wasn't really what I was looking for. I was hoping for a mindless tower defense game, but this actually takes a lot of input/thinking from the player.
Even though it wasn't what I wanted I will still give it a +1.

Deceptively evil game where you have to turn the area around to position your towers for the best defense.
Getting 3 stars is pretty difficult and don't expect to do it the first time around. My advice is to get the best towers first and then go back around and pick up all of the 3 stars.
A refreshingly different take on tower defense while still maintaining a bit of silliness.

An original little game that mixes puzzle and tower defense concepts. Graphics are tight, maybe a bit below genre average, but aren't bad. Mechanics is easy to learn: there are 7 kinds of common towers, each one can be enhanced 4 times, 6 power-ups, a coin system to buy upgrades, powers and 2 special towers, and few variety of enemies but are well designed. Player must prevent them waking a monster in the center of two spinning circles, wich can be rotated at will, radically changing roads and places of towers. There are 24 maps, each with 6 to 8 entrances. Maths of stats and costs are well implement.
The gameplay is fun, but is some restrictive: first enemy waves are worst because at beginning of every map there are few sites to build towers and those ones appears gradually so planing a good defense perimeter is unnecesary disturbing; all maps have a weak rearguard without tower locations; many times foes comming from 3 o 4 places at once; the tactic depends on spin quickly the maps at beginnings to assemble the routes and defenses and this may cause visual annoyances to player; towers unblocks for free progressively but the most powerfull must be bought ingame for a too expensive price. Complete the campaign with more of 80% achievements takes about 22 hours. Good for kids, cassuals and fans of puzzles, but the classic tower defense players surely feel frustrated.

Sleep Attack is a cute tower defense 'lite' with a twist... literally! If the game's core mechanic catches your fancy, you will definitely be addicted. At any rate, it's a decent entry into the genre that hits most of the basic marks. Sound, animation, and general atmosphere are all strengths. Also, this is one of the few mobile/PC crossover games on Steam that is worth playing. Pleasant surprises all around!
I can't believe I got this game for only $0.21 as part of a bundle. What a steal! Definitely worth trying if you can find it on sale.

Mobile games on Steam are a bit poo poo'd, and with fair reason considering some of the crap ones that have appeared on the store. But not all of them are bad, and some can bridge the gap between platforms pretty well. I think Sleep Attack manages this, thanks to a unique gimmick and nice visuals.
After a night of gaming and snack foods, Ubaldo, the big guy up there, falls asleep and is beset with bad dreams, represented by the monsters that come for him. Since it's a dream and all, they don't really have any unified theme: you'll fight guys with tiki masks, walking umbrellas, and cyborg snails. All the same though, I feel like they could have taken it a bit further; you never encounter anything you'd see at the end of the average Kirby game, sadly. At any rate, to deal with them you build towers, but they come at you from too many angles to cover ordinarily. That's where the game's gimmick comes in - each level is made up of two or three sections, and by clicking on them you can rotate them to change the paths and where enemies go. So you'll have to do things like force a large wave down the path with the most towers, or have a bulky enemy walk past your high damage ones.
This means strategies will be a bit different compared to other games of the genre, and Sleep Attack can be quite tricky at times, particularly if you're trying to perfect all the levels. They can be a bit long, too, with all of them containing 10 big waves. Fortunately there's a pause feature for when you need to think about your next move (it's disabled during the last wave, but simply grabbing a piece of the level pauses the enemies anyway, so it's a bit of a moot point), and after every level you gain some 'beans' which you can use to buy some limited use items, or save up to unlock a couple of the towers. I imagine there's an option to buy a bunch of them in the mobile version, but not here, and the game's perfectly beatable without them anyway.
Sleep Attack is priced at a modest seven dollars, and I got about 20 hours of gameplay out of it by the time I'd finished. It's been on sale for cheap a bunch, and has popped up in a few bundles, so you might have it lying around somewhere if not in your library. Either way, give it a try, it's an interesting deviation on the formula.

Sleep attack is mix between a puzzle game and a tower defense, and it does so well. You can tell alot of love was put into this game, the art is superb for what it is. However, the soundtrack did seem to be lacking in alot of areas, it seems to loop rather quickly. But the gameplay has good bit of variety in terms of your towers the enemy, also upgrading your towers gives a nice visual difference for each one, which I can appreciate . Also the whole "twist the map" thing is actually a good way to stop the gameplay from getting stale, you have to actively be involved if you want to move forward. If this were a mobile game I would definitely buy it, it has a the gimmicks of a good ol' time waster, however as a full PC release, me personally would not be interested. If they can port this it would be awesome to play this on my iPad or my phone.
Honestly, if you are into this type of genre be wary that the puzzle elements are pretty important, but for the price it's well worth a look at.

I've only played a few levels, and I will be honest, even a a tower defense fan this did not impress me, but it works, which says a lot these days.
The core TD gameplay is lackluster, the path the monster's take is pretty short, and the tower placement is limited to the few pre-determined spots, though more open up as the game progresses.
The key conceit of the game is that the map has rotatable rings, that you are required to pay attention to and spin to maximize the path the creatures take. Sadly in the game as far as it kept my attention, there was rarely a time when the best option wasn't very obvious, and there was no real creativity needed.
There are so many totally broken TD games out there though, that I have to give this a thumbs up. The graphics are cute, and the controls work fine, the sound is fine and there are a few different types of towers, and monsters. Not sure what else you could ask for.
