I enjoyed this game but there is the horrible feeling that the internet won't be alive for much longer, thanks for the internet everyone, you were a slight ray of light in my craphole of a life.
to get past the bottom bit on level 5 what I did there is a safe layer on just above it, fill it with as many blasters as you can and a maker on each side pouring down onto the pipe things, and after a while it will start to be destroyed and you can make your way down to the final creeper emitter
i really hope you continue to develop this game, its beautiful! i hope to see high scores (hopefully wont be hacked) and chievs!! and a buy mode with more weapons, but this is a hell of a start!
Write Steam and let them know you would like to see it!
