Great Game! The music was a nice choice but some sfx would have gone a long way... especially as there wasn't a lot of information feedback visually, like undead brute has no actual swing. I tried capturing the enemies when I had 4 already and despite being fully "bound" when I switched to the character I wanted to die the fully bound killed it but was not then bound and I had to attack again with bind. Not a flaw but it would be nice to "replace" a bound charcter.
The capturing of enemies reminded me of Thralls from Conan Exiles, I also like that you gave us the freedom to capture multiple of the same enemy.
It took me a moment to understand the Dash, much like the attacks was based on which direction my mouse was and not the direction my avatar was facing. Seeing as it has no attack it was hard to understand as I assumed it was a linear dash... but once I understood it was based on mouse location it was a much more versatile dash... I just wished there was more introduction for that... Also considering you have good art, I would have considered making a custom mouse cursor and then using it to show Dash direction facing.
Overall great game!
