It's official, I'm a sucker for 8-bit graphics. But you just took it to the next level. Despite the game's brutal but fair difficulty, I actually enjoyed myself, at least until I reached that platforming section with the pillars. *shudder...*
Now for the issues, there's nothing much but the controls, the controls... The 'build box' isn't always responsive and that has always led to me falling to my death countless times especially at parts where it should have been possible. Limiting the amount of blocks to be made to only 8 is one thing, but forcing players to calculate where to place the blocks especially through trial and error is a tad too much. That's the only issue I have.
That aside, the game's great. I can definitely picture many retro gaming fanatics storming this page. :)
