Gravity Circuit! This game captures the feel of Mega man Zero really well.

I recommend starting in hard mode since normal mode can easily be pushed through with upgrades.

Yeah… Zenfones were nice. Sad that ASUS didn’t put more effort into this product line.

Zenfone 11 and 12 are Gigantic in size.
8,9,10 Are small but not unlockable, also I think even ZF10 is reaching that 2 year software support too.
