Would be fun, but 2 very basic achievements are broken, and the developer is clearly unwilling to do anything about that. Also, the very last part of the game features a minigame that is massively unbalanced with the rest of the game as it is unbearably hard – at the same time there isn't even a way for me to figure out whether that part (the portal thing) actually nets you any reward for completing it (and that includes the forum)! As the time and effort you need to put in to get the roughly 700 points here is very high, I can only recommend you stay away from this broken mess, and all other products from this developer at all costs.
