Really like the base mechanics and art style, here are some thoughts on improvements:
- Make enemy classes much more distinct in appearance; can't tell the difference between a melee and ranged enemy until they start attacking.
- Make the shots from ranged enemies that ricochet off the shield do damage to enemies, that would be a neat little addition.
- Make it so that melee enemies can't attack you while you're on a ladder/climbing wall (ranged enemy attacks are fine, because they can be dodged, but melee attacks can't be...).
- Considering that this is such an early version of the game, it's hard to really give any solid feedback, because you might already plan to fix any issues I have with the game, but still these are the only things that really stood out to me (+ having to reload the page every time I died, but I assume that is only a flaw of this test...)
