I loved the concept of using the joined mechanic as a hindrance and a benefit. You really didn't want to be joined that way since the platforming felt better, but you needed the big brute to smash thru the level. The only real complaint I had was the controls when joined together since the game started to lag pretty heavily and made it near impossible to make some jumps. There might have been some optimization issues with the code to lead to that since I noticed how bloated the game file size was. Typically a game like this would be around 40MB or under and this is surpassing 130MB.
