I like this retro style mixed with a higher quality pixel art. The sfx just brought it together.
I must say thus the gui for the score and health are hard to see when playing (especially when thing spd up) and i think there no penalty for not killing the enemy in time as i haven't seen the health bar go down XD
That said seeing the far ground moving faster and faster made me focus less on those small detail and more on trying to kill! Owo
