Free replacement for minecraft app?

I have HATED minecraft for quite a while but lately i have been in the mood to play it.

Since i have hated it i don't want to spend money incase i return to hating it, so any free android apps?

I saw one called "uCraft A Minecraft Simulator". It's a kind of 2D mincraft, i haven't tried it but it has 4/5 stars
