A downloadable game for Windows

This is a mostly faithful remaster of the original I Wanna Be The Guy by Kayin, trying to balance the spirit of the original game with the desire for consistent physics like the fangames that came after, and fixing some of the jank.

- 200% scaling window mode for compatible displays
- 800x600 fullscreen mode for compatible displays

We hope you enjoy this remaster!

so when the game is done downloading it says "file moved or missing" and i cant find it in the files which means the file is deleting itself or getting deleted.

Probably Windows defender or your antivirus is flagging it as a virus  (false-positive), some gamemaker game have that issue

How do you use this with gm8emulator like the secret thing in the room of divine transportation says?

I try to just drag the game onto the exe and it opens for a second, loads something and closes about a second later.(I tried with destination and iwbtfangame and they opened fine, i also tried doing it in cmd prompt and the same thing happened).

The emulator's internals got overhauled pretty drastically during the summer, which broke compatibility. I've been meaning to fix that. Keep an eye on the emulator Discord, I'll get to that sooner rather than later.

Oh ok, thanks. I'll make sure to check that then.

I fixed it :)

I downloaded the zip package and extracted it. Trying to run "wine IWBTGR.exe" returns "Failed to load the game data. File seems corrupted." Behind that is a popup window reading "Error reading SplashEdit.Lines.Strings: RichEdit line insertion error."

The instructions indicate that I should be able to just download the package and run the executable, perhaps the instructions are unclear/incomplete?

We got someone to try the game on Mac, and they got it working using Wineskin Winery. I tried it myself on WSL, and while it didn't boot (I'm going to blame WSL), it got further than yours did.

While we aren't easily able to directly support non-Windows platforms, I'd be interested to hear what operating system you're running.

I fixed it on my end, the default wine prefix was misconfigured with respect to IWBTGR

When I try to open it says "File seems corrupted" :'c

ah, you probably have an old version of game maker 8. we use 8.1.141.

Oh thanks, now I can play it 

great work, considering the original IWBTG always prone to crash or get wonky.

Don't work with Xbox Elite controler 

I mapped shoot to K and am unable to shoot in the Zangief fight due to a division by 0

oh yeah we'll get to that in the next patch, sorry about that

are the zombies faster in the ghosts n goblins part? (faster than in the original i mean)


AMAZING game! makes you want to die every step of the way.  yay


Awesome and faithful. I love IWBTG and it is a classic of the genre, but the original game has technical flaws compared to fangames, this is awesome job.

Amazing remaster! I found something on the game intro but it’s not bad actually because I don’t really care.

The game has like a “censorship” mode to replace retard in the Zelda area but in the intro it says the word “shit” so I think it should also be censored if you want to add a censorship mode, but I don’t really care about it, considering how incredible this game is, and I don’t have any complaints about this.

So yeah, with that said, great remaster, I’m loving this!


We censored the "R word" specifically because it's derogatory. It's a joke Kayin regrets making now (and would have patched out of the game himself) but it's in the game as an option for the sake of preservation which I feel is the best compromise (he approved this too). The usage of shit is incredibly minor and it's not offensive really so I don't feel it really needs to be accounted for.

Thanks for your thoughts!

Any chance of a macOS port? I'm happy to lend a hand.

(btw for anyone wondering, it runs ok on Crossover but I had some lag)


No, sorry, Game Maker for Mac is based on GM7 and we use GM8.2. Try using wine! I've had reports that GM8 games work fine through it.

i like it!

It says the game was updated, what changed? Also will you be doing a remaster of IWBTG Gaiden in the future?

(1 edit) (+1)

Very small micropatches like a very rare bug with the bomb where it would clip through the floor if you did something unintentional and unhelpful. Nothing super important.

Also, Gaiden isn't really a full game yet (and probably wont ever be) so I don't think there's really too much of a reason to remaster it
