TL;DR: This game is perfect for people who want a Hotline Miami-esque ego shooter. Its fast, has a driving soundtrack and a variety of tools to fit your personal playstyle. And shoes! And who doesn't love shoes.
Anger Foot is what you get when you take Hotline Miami, change the perspective from Top-Down to Ego, use a 3D-Cartoon Artstyle instead of Pixel Graphic, and switch out the Synthwave for Rave Music.
This is not me saying that Anger Foot is a total Hotline Miami ripoff, on the one hand, because I don't like the word ripoff, on the other hand, because Anger Foot has its own identity as a game already so that Hotline Miami can be best described as an inspiration and not as a blueprint.
For example, the "One Hit = Death" policy of HM doesn't apply to Anger Foot. You die from one melee hit, sure, but you can take two shots before you go down, except for when you get hit by the full blast of a shotgun.
This brings me to the enemies: Anger Foot has around 10 distinct enemy types, which all die in one hit, none of the overpowered and all unique. The most common and the earliest introduced are the bat crocodiles and the pistol fish, but there are also foes that use more ways to fight than simple hitting and shooting.
You will probably do a fair bit of shooting yourself, in fact, all guns of the enemies are available to you. There are four guns in total. You have the pistol, which is your slow but accurate option, the SMG, which fires fast but is not accurate on distance, the shotgun, which spreads but has a short range, and the plunger grappling hook, which is not really a gun, because it's shot a grappling hook that pulls enemies toward you.
All guns work as you imagine and all of them have their place in gameplay, my least favorite being the shotgun because while it spreads, it has the slowest firing rate, which is quite disadvantageous in the later levels where you have to fight more than five enemies at once in close spaces at some points.
Speaking of slow, while there is no highscore system, the game counts how many enemies you have killed in a level and how long it did take you to complete it.
Some of the unlockables are explicitly tied to your best time. These unlockables come, fitting to the title of the game in the form of shoes, which give you special abilities, comparable to the masks in Hotline Miami.
These shoes are unlocked by earning medals, essentially the achievements of this game. You get these for beating levels in a specific time or killing a number of enemies with headshots or exploding barrels, among others, which of course adds to the replayability of the levels, next to the rush and the need to beat your best time.
I only got one pair of shoes so far, the Air Violence, which fill up your gun with every kill. By the way, the devs totally missed the chance to call them Pumped Up Kicks, just saying.
When this seems to you like an ability with zero upsides, then because I didn't mention the attack which this game owes his title from, the kick.
The kick kills every enemy with one hit and is also the only way to open doors and therefore the only way to get through the levels. You can kick everywhere at any time, given that you are still alive, which is very useful when you ran out of ammo or are otherwise more inclined to melee. One enemy type even can only be killed by a kick attack. It is possible to get through all levels with just this attack, which I can see myself doing someday, because jump-kicking in this game is so darn fun.
The only other attack besides the kick is throwing your guns, however, this just stuns for a short time the enemies, so you have to kill them off otherwise. Never really used it that much, but its there, so if you into that stuff, go for it.
If you ask yourself why I have not mentioned the plot of the game till this point then this is because the game hasn't one. Maybe some very minor enviormental storytelling and there is a sequence teasing at a narrative at the end, but otherwise, you are just one guy going into sewers and apartment buildings to kill the partying crowd.
To be honest, I don't need more story than that, but I am still curious if they will add a full narrative in the full release, just because Hotline Miami started out relatively senseless, but had so much more under the hood and I would like to see that again.
But that would be all. Other than the fact that it is a bit too easy to camp behind doors and wait for enemies to come to you, which is counteracted by some enemy types, I don't have much to criticize.
Honestly, add an online leaderboard and you would already have a solid 3 bucks game to publish on Steam.
