Out of all the idle game genre I've played through flash games, mobile games, etc. This is one of the most interesting one! At this stage of the game, right now is alright. The game has potential, especially with this kind of concept. Sadly there would no longer have any updates, as it's said on the description.
The only sad thing about this, is that it's really that short, excluding the reset button. A total of 7 kinds of stages only, seemed a bit too short. That you'd only have to achieve solely like a power gaming kind of play. Some items are already quite useless for the Soulbound combinations. Not to mention how ridiculously high it cost to combining items with a range type of weapons, most probably the cost of increasing the range. Made me abandon that kind of weapon and create a much more better one.
But despite that, the game really is enjoying. Already had my 10th reset, and 1 full reset (data reset) just to play the whole game again. Hopefully It'll be all covered up, through the many updates yet to come. That is if the creator of the game is willing to continue about it or at least make a better sequel of it :)
