Ok, so in terms of graphics you nailed it. Really impressive.
I have 2 issues with game.
-The red shooting enemy has no indication as to when he is shooting. Visual and audio cue are really important when it's 1 hit and you die - which is the second issue. You could have the blob lose mass and it will be fine. But maybe I just suck.
Even with those issues I still had fun.
Well done!
