I've played the public 0.9.8 releases of Parachute and Octopus and the haptics seem to be no longer working on 0.9.8 on my Galaxy S7 Edge.
The previous test versions had this working well on both those titles. I've tried pushing the vibration slider from left to right and middle and checked my phone settings to make sure haptics are enabled. I tried to access the older test versions just to make sure but you seem to have removed them (including the older Octopus you provided a link for me in a forum message.)
