Congratulations for this game! I also have the old speccy version, and this one looks gorgeous. I like it a lot.
However, I have experienced a small glitch. The first time I installed the game, when I pressed fire (space) to start the game, there was a ~8 seconds delay where the menu seemed to be stuck/hung. After this initial delay, all next times I have started the game, there has been no delay at all.
I have been able to reproduce the glitch, copying the shovel folder from the zip and running it again. Again, the same 8 second delay at the first execution.
Could it be an issue with file access, maybe some file which is written the first time and not the next ones?
I am running on a N-GO with firmware 1.31 and core 3.01.10.
