Sadly these are as-is. I no longer have the source for this game. The original Derelict was made in 10 days for GBJam5, and the EX version was near completion, however the escape sequence was the last thing I had worked on before it became corrupted :(
I am~ I’ve spent the past year and a half working on a parody/homage to C*stlevania and other NES titles called Simon Quest’s Transylvania Adventure - I post updates pretty regularly on my twitter.
