Fantastic game except you could fix some things
1. First Boss took me too many times to kill, even though I hadn't bought anything (just had lvled to 8 when I took him on)
2. Second Boss nearly impossible to beat, it spams its ultimate move way too much, I got hit four consecutive times. I spent most of the fight healing than doing damage to it. (I killed it eventually. Tip, to get maximum damage, 1st Skill, then 2nd Skill)
3. It got stuck after I killed the treasure chest, took me several attempts and lot of night crawler things before it let me leave. (Afterwards, I read the beastiary, everytime it launched an attack, I was supposed to get more money)
4. Never bought Battle Mode because it was too expensive
5. Death guy on train ultimate move deals up to more than 130 damage, which is over halfway of life, plus everytime he does that, you waste too much time trying to heal yourself while he absorbs it back from you. Sometimes he uses it twice in a row, so if you were on half health, 115hp, first time, deals 100 damage, heal 70, (75 remaining), again deals another 90 damage, instant death.
6. Most times, he absorbs more health from you, than your damage dealt to him. (I had fine rapier and he still dealt 40s while I dealt 30-50s).
After that I stopped playing, game takes too fricking long.
Also, to people reading this. My advice, just keep killing the weak monsters near the save point. It helps loads.
