It's not that bad since your just starting a game and finishing it.
The art is very classic generic look like it came from the gameboy lol. No problem there suits fine with the game itself. Sadly the music isn't there. Also the exploding sound effects is getting annoying maybe it's just me so I didn't make that a play on your score.
The game is hard. Let's get to the point. Level 1 is hard. AI is strong and quite smart and I have to get used to the strange controls. Normally WSAD is to move THAT direction... but now you have to TURN that direction which makes it ever so slightly harder since the enemies move differently-ish.
Hope to see more futures... but in reality this game doesn't have much to offer. Honestly would't play it again to waste some time. But it's a good starter.
