Hi Ogamo,
I'm glad you were having fun! Thank you for your notes on the resolution issue and the sound sound effects. The sound effects are meant to be a useful indicator for when the Death Wall is eating a lot of blocks and speeding up but at the moment it applies equally to grey and coloured blocks (but it only speeds up with coloured ones). Internally we had discussed representing this by having little puffs of binary pop out from the left of screen whenever a coloured block was destroyed off-screen. Maybe this could have a much more subtle sound effect. I think if we added that we could then have the brick explosion noise fall off with distance from the wall as you would still have a moment-by-moment visual and audio feedback of your performance. Do you think you would prefer something like this?
Thanks again for taking the time to try the game out and provide feedback, we appreciate it a lot! :)
