Gun Monkey felt broken and unfinished when I tried it... the battles are all 1 vs 1 as far as I know. You need to collect blue cubes in order to bring your opponent energy to zero and win but you need to press down to collect those blue cubes and the "too hard to master" controls gives you the impression that you are walking on ice all the time. You will have to reset your keys because having to press "e" to fire your gun while moving around with "wasd" keys feels counterintuitive... why they selected those as default key bind beats me.
The music is repetitive and the level design feel bland... I didn't know procedurally–generated was an excuse to not add strategy to the game. I kind of dig the character design but the fact that you can only shoot left or right and not aim your gun properly bugs me. The visuals are too minimalistic for this sort of game... it compliments the game about as well as a picasso in the middle of some amusement park.
The weapons are probably the strongest point in this game since killing your opponent seems to be the only enjoyable thing to do but this being said the bombs and mines are overpowered to the point of absurdness because most of the time you will end up blowing yourself up.
After each game you earn or lose money and there is a shop in the "my team" section where you can purchase some upgrade and become a little bit more of a treath to others. The items you own can be unequipped but once you remove them they are discarted and I don't even understand how thos items work and no information is given as to how they affect the game. Shady to say the least.
Also, most of the time your opponents will simply disconect when they are about to lose. No punitive system is present to prevent players from doing so and if a player disconect that match is simply voided.
To me it feels like Gun Monkey was poorly designed in order to keep people from becoming good at it but some poor souls are trapped in this game and are still trying hard to become better at it every day.
I give Gun Monkey 4/10
