TRAPPED! - An arcade bullet hell

Trapped is an arcade game where you are, yes, trapped in a room that gets increasingly filled with obstacles that (for the moment) shoot at you.

Your objective is to grab as many coins as possible!

The game is playable with a keyboard or with a gamepad, and you can use a dash that grants you brief invulnerability by pressing space or "x" on a playstation controller ("A" for Xbox).

This is a game idea i've had for a while and ultimately decided to make a prototype for a few weeks ago. This is only a very early prototype of the core gameplay loop made in a few hours, but i'd like to know what people think about the idea :)
