In order to allow you a bit of time to orient yourself in the death world, and to highlight that there was a difference and not just a pallet swap, I made a simple transition when you die. The screen splits in 2, and the sides uncover the next stage. It looks like this:
I liked this transition so much, however, that I put it in the beginning of the menus also, and at the beginning of my end-game score chart. O, I forgot to tell you about that. Now, when the time ends, you get a screen like this:
Next thing I will do is add this to a high score list, which will be displayed on the main window. I am still thinking where to put the controls. I think I might display them at the bottom when you start the game.
I also made a change to the way coins work. Earlier, you had to collect the coins from enemies to get score, but they where kind of difficult to get, quickly flooding the level with coins, making collecting more important then shooting and making the game run slow. Now, you get half the score upon killing the enemy, and half upon collecting the coins. The coins disappear if you don't collect them in 4 seconds. This way, you can just focus on shooting stuff, and the coins provide a incentive to move around a little but, but you still need to keep shooting.
I also recorded a gameplay video:
