Congrats on finishing this- the game looks and sounds fantastic (in particular, hearing the main menu music in Megadrive quality did strange things to me!). There was one bug that finished me though- I was caught by the troll thing on the ledge above the spanner and died. Instead of getting a last go, the the foreground drawings of the characters staying showing, while I remained a lifeless eggshell and had to force the game closed.
Can definitely tell a lot of love and hard work has gone into this and it's only a shame there aren't more Dizzy games on itch- could give the Oliver Twins a whole new audience!
