I'm really enjoying Anger Foot. It's fast-paced, fun, challenging and full of silly personality. It also runs very well on my M1 Mac Mini, with the only slowdown occurring in that big misty room full of dinosaur thugs.
I just have a couple of suggestions.
You should be able to shoot around the riot ducks' shields. The first time I encountered them, I naturally shot at their feet, but the bullets bounced off as if I'd aimed at their shields. The shield shouldn't make them completely invincible.
Perhaps grenade blasts should turn those wheels? This would add an extra note of strategy and unpredictability.
I don't know how you'd implement this, but it would be funny and immersive if the music in a given room becomes muffled if the speakers fall on their face. :)
As for future compatibility, does the Mac version use Metal or OpenGL? If it uses Metal, then you have nothing to worry about, but if it uses OpenGL, I would advise converting the Mac version to Metal. Apple hasn't updated OpenGL in Mac OS since 10.11 El Capitan (soon to be eight OS versions ago), and it's only a matter of time before they discontinue it altogether. :(
(By the way, is Floor 3 of Narcotomi Tower glitched? I'm sure I've checked every inch of that level, but I'm still down one kill every time)
Anyway, Anger Foot is really fun, and I'm looking forward to the completed version. :D
