The game is pretty solid and straight forward. If I had to nitpick there are a few things that were off.Text resolution was a bit too small / pixelated for me to be able to read in full screen in the intro screen. The abilities didn't have a cool down times so I didn't know when I could use certain spells. The toxic / poison spell was pretty OP, it'd just melt the dragon boss in a few seconds. The tree pop in was a little distracting for me personally.
Those are just me picking out little things though. I think this would be fun with some friends / some sort of cooperative play if you plan on working on this project more.
