The Amiga games I remember most fondly from my childhood (and thus the Amiga games that you absolutely need to take a look at) are:
Speedball 2: Brutal Deluxe
Sensible World of Soccer
Xenon 2 Megablast
Pinball Dreams / Fantasies
I much preferred the original C64 version of Paradroid to the Amiga version (Paradroid 90). The updated visuals actually worked against the gameplay imo.
EDIT: Completely forgot about Shadow of the Beast II. First game I ever played on my Amiga 500 - never saw much of the game as I was so bad at it, but the intro had smoke coming out of a chimney and EVERYTHING.
@DarthOrange: Thanks for the feedback. Much appreciated! I think because I test my own levels almost every single time I change anything about them I tend to get too good at them and, as a result, make them overly challenging. Your suggestion to use some infinite life checkpoints is definitely a good one. I'll be sure to do that if/when I update the level.
Took my first full LBP Vita level live last night and, some 12 hours later, only one person has played it. (One of the developers, who responded to me on Twitter.) If you've got a few minutes to spare, I'd really appreciate you taking the time to play and offer feedback on it. I plan to keep creating levels, but if folks don't like this one then I obviously need to try something different.
