>>714320462 (OP)I looked at a friend play it and it looks plain tedious. The inverted levels are just an excuse to make you play the levels a second time. The wumpa fruit gems are an excuse to double the total amount of gems without doing anything.
I play a lot of platformers so I think I can form a general opinion just looking at it.
Despite of that, the core of the game actually looks fine and better than I expected from a sequel so many years later. Removing the lives system and changing it to what the game has was fantastic.
