I enjoyed the nostalgia feel. I didn't get sucked into it to play past the first boss but it was interesting enough to try and I liked how you did boss mechanics with the tree having stomp waves.
I messed around gaining stats on humans & orcs until I reincarnated as an elf after a few deaths, then I just went and killed everyone from range with elf and killed the boss too all as first time elf with no deaths.
I think the elf is pretty overpowered simply because of the usage of range and AI not responding optimally to ranged attacks, also pretty easy to dodge boss wave if you were shooting from max range.
I'd add an icon for each ability on screen, to remind and encourage ability use. I finished the tree boss with arrows and then remembered I hadn't tried using abilities. xD
Fun enough game, good job on the jam! :)
