Far be it from me to criticise free games, so i'll offer some 'friendly advice' instead:
Less of the 'it's an RPG!' jokes. We get it, it wears thin. Although i loved the 'i'm four men!' line, paired with the 'am i actually a feminist who believes all men or misogynistic or am i just criticising those feminists?' dialogues... it gets old.
Maybe look at reworking the control system. holding down E or A or whatever else to see what items do is annoying, and you often have to trust descriptions rather than seeing stats. Likewise, i would prefer not t have to switch between keyboard and mouse all the time. Yes, the X and Z keys can be used, but not always, for example on the inventory screen, and it's just a bit unrefined.
Make battles faster. Random battles are always going to be a pain, i'll admit, but these were excruciating.
i think that's it..
Yeah, what everyone else said. It's awesome, well thought out et al, but the fact that the more bots you have the more they start to get that little bit off can get frustrating, especially on level 12.
Yeah, inventory is kinda crap, the interface for it's a little fiddly, and with so many weapons it's difficult to know what to discard sometimes. i guess that's pretty much par for the course though. i like having a tank warrior, a strength warrior, a cleric (cos i'm a pussy and can't do without the security of my healers) and a rogue. i agree that more enemies would be great, varying sets only until 5 levels is a little lazy, perhaps :P
