Challenging and fun

I read the developers response to another reviewer criticising the amount of ads. I personally don’t think there’s many ads at all and I think thing the developer has made a really fun game and kept it free which he should be commended for. Well done!

After playing the game for a while I have noticed that some of the clues are ridiculous. For example level 32 shows you something resembling a bra with a dot below it. Well if you draw these as instructed they just fall to the ground without touching the magnets. This is my only gripe but still enjoying the game.

Physics not quite correct and needs better support for iPhone X/XS/XR

Others have already mentioned the issues with playing on an iPhone X, so I’ll skip to the issue that bothers me the most: the physics is not quite correct. You’d expect that bigger/denser blobs would have more mass and, hence, more momentum (for a given speed) but that isn’t always the case and changes from level to level. Also, it’s not entirely clear if there’s gravity or not. If I drop a blob from the top, it doesn’t seem to accelerate but only to move at a constant speed - acceleration is important if I’m trying to judge what height I need to drop something from. Another issue is that collisions are unpredictable in terms of their coefficients of restitution. Sometimes a collision appears to be elastic, other times hardly so. The same happens with friction. A ball gets hit hard but rolls very slowly in one level but gets hit softly and rolls fast in another. These variations from level to level make the behaviour of what I draw very unpredictable, making me waste time to figure out what set of physical parameters a given level uses. If you’re going to claim that this is a physics-based game, then set the physical parameters once and stick to them, the same for all levels. Otherwise, this is a very creative and addictive game.

One of the best

Anyone whinging that this game is too hard, you need to delete it and get an easier game, I can see that this game has been carefully designed to challenge the player. On another point anyone whinging that there are too many ads - BUY THE GAME! Nothing is free in this life, when I was growing up these were called playable demos, you got a couple of levels to decide if you want to BUY it, it’s the same with the ads, a gentle reminder to BUY THE GAME... this game is awesome and I have played this and Shatterbrain to completion with full 3 stars :) more like this please!
