@Logan: If I may be so bold, I have a bunch of other suggestions.
- Make it so you can use the spacebar to shoot as well as Ctrl. I instinctively go for space whenever the level begins only to realise a split-second later that I need to be holding Ctrl.
- The gameplay mechanic with the Core pieces is too important IMO to be a completely random drop. On one game I didn’t get to upgrade my core by the 4th level and it was nigh on impossible to all the blocks in a wave. Perhaps make it a reward that drops when you’ve cleared a certain number of waves OR (heresy ahead) give the player one for free after clearing each level.
- Hold off on finishing the level until the screen is clear. There’s nothing more frustrating than just clearing a wave and racing to grab the powerup (triply so if it dropped a Core) only to have the Level Clear box pop up.

I don’t know how hard it would be to get all those working in your game (my fields of expertise are C++ and to an extent C#, go Qantm College) but I think it would make the game more skill-based and less reliant on chance (and make me feel less like an idiot for always hitting space).

I’ll admit it’s probably the weaker of the three games, but I accepted the fact when I started the feature there’d be up and down weeks. I think Blockshooter works best as a proof-of-concept. :)

And all three of your suggestions are good ones!

@Vangalorr: Hmm, that’s very odd. I’ve used Ctrl since the start of development and it definitely works! Try pressing the Ctrl on the left side of the keyboard. :P

Three issues I’ve found so far though.
1. If the blocks are coming down on the far right and they’re close to the bottom it’s possible to get pinned and cry (not really) as you watch your score plummet.
2. There are some blocks spawning off the right side of the map where the player can’t shoot them.
3. Can you make the images save to where the game is run from rather than the root?

Ctrl doesn’t seem to fire the weapons for me, can you please do a quick check to make sure this works for you.
