Hi guys,
I decided to see if I could squeeze a second MSXDev'17 entry and I've been working on it since I completed Tales of Popolon. I just finished testing the first beta release!! It's called "XSpelunker" and it's a a mix between Spelunky and Livingstone Supongo: procedurally generated maps, permadeath (you need to start from scratch every time), and pretty hard platforming action!
Youtube video of intro and gameplay here: https://www.youtube.com/watch?v=OaTt0T8O0N0
ROM available here: https://github.com/santiontanon/xspelunker/releases
And, instructions, and complete source code here: https://github.com/santiontanon/xspelunker
It's a pretty short game (beating it once you master it can take between 7 - 10 minutes), but it might take several hours to master it in order to do so, since, depending on how enemies are spawned, it can get quite brutal!! :)
Note: the character can do quite a lot of things (attacking, jumping, climbing, swimming, crouching, picking/dropping/using objects, etc.), and I tried to make everything controllable with just 2 action buttons (so, it can be played with standard 2-button joysticks). So, reading the instructions for controls is highly recommended (here: https://github.com/santiontanon/xspelunker ). For example, you can "double click" up/left/right when climbing on ropes for jumping/dropping from them.
