Congrats for your Spice Invaderz! I must tell you that the Invaders are really not my thing, but this particular one is the best I have played. The innovation of having the ?mother ship? sending a missile is excellent, and even if it is a difficult game, it is playable, which is more than I can say about the majority of the Invaders games.
Suggestion: When there is just 2 or 3 Aliens left, the speed of the game gets crazy, and when just 1 is left the speed gets impossible. I would decrease it a bit.
Question: I am playing with CSpect, and I confirm that this game does not work when placed inside the Next SD virtual drive, having to be placed in the CSpect folder itself and be invoked by a script that starts CSpect. Can you explain why this happens? I have just seen this in other 2 games, Outer Intruders https://oscarbraindead.itch.io/outerintrudersand Nexttanks https://oscarbraindead.itch.io/nexttanks, and the only commonality I find is that all these 3 games haven been developed with Boriel's BASIC? Maybe what triggers this issue comes from Boriel?!
