In normal mode there seems to be no use for the money
the normal mode also seems rather unfinished with the end of a level having a door that is apparently still under development.
endless mode is rather repetitive and uninteresting, and once you got your 500 money to buy a laser, there is no further improvement you can get.
there seems to be no real punishment for dying, aside from maybe being set back a bit, but especially since killed enemies stay dead, that's very minor,
when using the buttons to purchase the laser, mute the music, and to skip a wave, the character becomes immovable (although it is resolved by clicking outside of the game and then in the game, but it really shouldn't happen to begin with)
the 'connect to Cocoon JS' button on the menu doesn't seem to do anything at all
when close enough to a wall or floor, the gun/laser can shoot trough it without an enemy being able to shoot you.
you definitely made improvements from the earlier version, and although you fixed most of the problems I pointed out last time, new ones have been created in this newer version.
It also still seems to be in development, so hopefully you'll improve and extend the game further,
