Thanks so so much! Glad you had some fun with it. Yep the controls definitely could do with some tweaking, I do have some ideas on how I could have smoothed things over a bit.
To be honest the achievements system was a prepared resource I had. Unfortunately there wouldn't have been time to build it from the ground up otherwise. I thought I had removed it during crunch time though as a "nice to have but not required" feature so I was surprised to see it mentioned hehe :D
