Very well polished game. It has issues but it's very beautiful at first sight. The sound design isn't overdone, it's feels just right. Physics can be a bit weird sometimes but perfecting physics in this type of game in under one week is no easy task to be sure. Visually, this game is a gem. One thing however I have to mention is that visibility is a bit weak at times. The vignette effect could be a bit weaker and the FOV could be cranked up but I believe it would hurt readability because of the low resolution, things on the sides of the screen would be very distorted. (Devil Daggers for example has a low resolution that is still far more than 160x144 and it has big issues above 90)
Solid entry, all in all
