Came here from ThioJoe's YT channel- never knew this existed, I've been in IT for decades, am an avid gamer & I can't recall ever seeing a game in PDF format before.(packaging a autoloading ver of sumatra with it is also a really nice touch) Now we just need to see if you can make it run DOOM lol. I think you'd have 2 world firsts then...
Looks like it'll be fun to play. For some reason this reminded me of when I got contacted by the creator of RPG Maker '95 out of the blue because I had used nothing but items triggering each other through local switches to give a skill to a character they could use in battle if they were holding the item. Transferring the item to another character removed it from the one that originally had it & instead worked for the new character. He told me what I had posted was impossible- (the engine only had local switches, no global ones, & didn't have any variables at all. No local, no global, not even preset addressable ones.) So I sent him the game file. He apologized for being wrong publicly, & played what I had of the game & liked it. 5 other friends of mine & I were working on it, but about 4 month's later my friends sister's friend got a boot sector virus that killed the HD. And back then I didn't know how to repair something like that like I do now. Our game was almost 700MB, <mostly because of custom music in huge .wav file format<the engine didn't allow MP3 until I think RPG Maker XP or VX? Anyway, like idiots we didn't have backups & although we were saving up for a CD/RW burner it was about $350.00. We were still in school & weren't old enough to work part time yet, & odd jobs didn't make enough.
Anyhow, cool project. Keep up with that kind of creativity & critical thinking & I fully expect you to do something else completely unique & interesting. I appreciate the time & effort this must have taken- well done, & good luck with your future endeavors.
