This is a fun platformer game in which you also have level-up system. There is a story in this game, but I didn’t feel that at all during playing this game. You’ll just try to beat every 3 levels in one run because the save point is at every 3 levels and just before the boss fight.
There are two important currencies in this game, the first one is experience points that you get from beating monsters. You use experience points to get the option to increase one of three stats (STR/VIT/DEX). The second one is money. You’ll get money from smashing items and killing monsters. The most important resource for money will be the quests you will automatically get during this game. The quests will have objectives like “kill monster Z 5 times, smash statues X amount of time, stuff like that. With money you’ll buy new equipment to increase your stats a lot more than you’ll with leveling up. I would highly suggest looking at the new quest every time you completed one because I didn’t and I found out the monsters of my quests were around level 14 while I was already at level 50. There is level selection, so you can easily go back, but since it is the main way to get a lot of money very quickly it is much easier to focus on the quests while you’re exploring around that level than have to go back just for the quests.
The achievements for this game are very easy and you’ll get them by just playing the game. If you’re extremely good you might have not died 25 times before beating the final boss, but I’m sure you’ll be able to kill yourself a few times on purpose ;).
