Great concept, but I feel like it wasn't playtested enough.
When shooting when your character is next to a wall the bullet just dissappears.
Biggest problem probably is that when you pick up a bunch of credits at the same time the sounds stack and it can get extremely loud to the point it hurt my ears a bit.
Bullets need a proper texture and in my opinion should be bigger but slower. Also more impact when shooting/killing enemies would greatly help.
Mainly needs more polish and bugfixing, but could be a great game!
