Played it all the way through. General comments:
- I did not notice that there was a shield ability, but I never needed it. Perhaps in harder levels it'd be useful.
- The animations look good.
- It's satisfying to line up the right click ability so that it hits a bunch of mobs at once.
- I kinda wished I could move while using my abilities (swiping, throwing the spear/firework, and doing the right click ability).
- It seemed like mouse only had 2/3 of the abilities. Perhaps mapping middle-mouse to the 3rd ability would be nice, if you want to have the option to play with mouse. After switching to use the keyboard, I did not try to use the mouse again because I wanted to have all abilities at my disposal.
- I couldn't tell why I couldn't move on from a certain stage to the next at first. I guessed that I had to kill all the mobs, but honestly I'm still not sure.
- The title card art and music is excellent.
- Nitpick for the demo experience: Would be nice if you can pause and see controls while in the game, rather than having to go to main menu to see controls.
