Fantastic. I think the only the only thing that can be improved is the articulation on the drums.

there is a lot of chaos..
could be a bit cleaner with the same energy or even more
for the rest it reminds me a bit of plants vs zombies in some ways..

i do like it a lot
but it could have been better

[Also you could have done way more with the part around 1:53]
that part is actually fire

I like this a bunch, but this sounds like the *base* song for something greater.
I saw a video about "interactive" music, and I could totally see new instruments being added when you put in different party members or do certain spells or special moves.

If this were in a JRPG it would be the battle music in a cave or something similar, I bet. Great job!

(if you have 20-ish minutes for that video I mentioned here you go: https://www.youtube.com/watch?v=GaBJ2C7Am6E)

Sounds pretty calm and casual for being a battle theme. I like the melody but it doesn't strike me as a "JRPG-Style". Could definitely add a bit more power to it, maybe a bit of organ in the background and add more active bassline.

i think it could be better but its still really good
