First of all, as a non artist Im really glad you liked my drawings, I was a little worried about them.
For the controls I chose left and right arrows thinking about porting the game to android in a future and having only two buttons made it easier to play with your thumbs (In my head at least xD), but maybe you are right, it is kind of unconfortable to cycle through the party.
Archer REALLY does need more use, and no, there is nothing else later hahah. I was planning to add a lot more enemies tho, I just wanted to see if the core game worked and if the mechanic was fun before doing that.
Ive been thinking in three more enemies especifically for the archer: 1) a spider that falls from above and at a certain point stops and starts shooting or something (the archer could kill the spider, destroy the spiderweb "bullets" and maybe the knigt could also protect the team from the bullets with his shield idk). 2) Some kind of bird that comes flying and at some point of its trajectory attacks (only the archer can kill it) 3) this is my favorite, an ogre twice the size of the other enemies that can only be killed hitting him in the eye or face (only the archer can shoot in that angle).
But yeah I was thinking of adding more enemies for all characters (maybe for some you have to combine your heros, like destroying a protecting field with a fireball and then killing the monster with the knight). The idea is to introduce new enemies little by little to add on the difficulty.
And Im working on sound effects right now before everything else. I intended to put some on the demo, but I had some issues with the build :( The music will be a lot more complicated though, everything a make sounds just awfull!
Thanks a lot for the feedback man, it was really helpfull!
