i finished the game in around 7 hours,basicaly what i said before still applies because the game never moves from the "buy low,sell high" concept
i like the game because it is somewhat original in concept and i have a weak spot for any game where you power level,but at the same time it is so simple in concept and so monotonus it's hard for me to say "this is good! you guys should give this a try!" the whole dungeon crawling segments become pointless in the later part of the game (to show this there are only 2 basic dungeons,one that is 15 floor long and another that is 30 floor long) because the stuff you can buy and resell give you a better income than the crappy item you find in the dungeon
there are different character to use in dungeon but by the time you unlock them,the basic swordman you have is so strong,you don't have any reason to use the other (coincidentaly he's also the one with the better stats)
the other thing that ticks me off is that you should play the game the opposite way the tutorial teach you to play,the tutorial makes it sounds like you should always try to shot high and haggle to get more bangs out of your item but you get a bonus to your experience point everytime you sell an item without haggling,ultimately this bonus gives you quicker access to more expensive item,which in turn racks you a lot more money than you would have got if you just haggled all the time for cheap items,why the game never seems to make any straight mention of this bonus is a mystery
mmm... what else? after finishing the game there is
1) a new game+ mode where you begin anew with your level and your items
2) an endless mode where you can play without worrying about reaching any money target (by the way this is probably the best time to add the fact that this target gets a CRAZY increase spike in the last segment of the game) there are also some extra dungeons to explore altough i doubt they are worth the time
3) a survival mode which plays like the normal game but after reaching the last money target,you get another higher target until you can't pay anymore
tl;dr version
it's cool but repetitive,probably not worth 15 quids,i'm a dirty

who hates those poor indie developers
