A downloadable game for Windows

About This Project

This is a personal fan game of mine that I had been working on for a working / interactive screen cosplay! I'm a huge fan of Undertale and this boss battle in particular, since it was such a departure from the rest of the game. So, obviously that meant that I had to remake it from scratch.


How To Play

Move: Arrow Keys
Action: Z or Enter
Fullscreen Toggle: F4
Dodge as much as you can, call out for help, and fight to take down Flowey!


Visual Epilepsy Warning

Warning! This game contains flashing lights, static, and other such patterns, which could be potentially harmful to those who experience visual epilepsy! Play at your own risk, and take care!


Spoilers

This fan game has massive spoilers for the neutral ending of Undertale! So, if you haven't already, do yourself a favor and go play Undertale! It holds a very special place in my heart, and perhaps it will in yours, too.


Further Development Notice:

Sorry, but I don't have any plans to update this game any further, or make any ports of it to other platforms. My apologies to those who have been asking for that with no answers, but please don't wait with bated breath.


Antivirus Flagging Notice:

I'm pretty darn certain that this executable is virus/malware free, but some antiviruses may still flag it as a threat. This is not uncommon with executables compiled using GameMaker Studio. To combat this, I've included a downloadable ZIP file with an included readme file, which hopefully may help those who are getting their executables deleted/flagged. Additionally, if Chrome is denying you the ability to download either file, you can choose to allow the download via the menu button to the right of the download on the bottom of the Chrome window (if I remember correctly). However, please do report any high risk warnings if you come across any in the comments section below.

BARKSCRIPT

please answer

i’m a beginner programmer and i saw you wrote you work on gms

sooo i’m sorry if this question is strange but can you please share your gms file (i mean the one you can open in the programme)

i swear i won’t steal this battle system, it just seems so great and i’d like to see how it works and make mine looking at yours

and yeah there are lots of engines for that out there but most of them are pixelated, not battle-only and have a ton of things i don’t need which ConFUSe mE

but if you choose not to i understand!!!!!!!!!!!so yeah

(AND YES THIS WAS MADE LIKE A LOONG TIME AGO I KNOW ITS JUST THAT PPL KEEP COMMENTING :D)

hi nikul_l,

while i'm glad you're seeking resources and i'm sure you truly wouldn't steal anything from it, unfortunately, i don't plan on sharing the project file publicly. i do however wish you luck on learning how to program! i'm sure with time and practice, you can make the game of your dreams.

don't give up!

omg you’re so kind!!!!!! i totally understand if you don’t plan on doing so, i’m sorry and thank you for your reply!!!

Guys... I found a way if your download ends in a network fail... If you're using the latest Google, just go to downloads and try again! I can't help the antivirus... Just sayin...

um can you put it in a compressed zip or something cause my anti virus deleted it

I want to practice, especially after my neutral run...

My Antivirus says it gives VIRUS!!

do you have windows 10

yes

(-1)

NYEHEHEHEHE HUMAN! I AM VERY GOOD AT THIS GAME! I HAVE COMPLETED IT ON NORMAL MODE FIRST TRY! NYEHEHEHEHE!

(-1)

I already did this just for you, brother.

(-1)

My thing says it has malware on it. So....

(-1)

well, gamemaker's executables have a tendency to set off false alarms on anti-virus/malware, so that might be what the issue is.  that being said, i assure you i haven't put any malware on this intentionally, but if there is something serious causing your anti-virus or anti-malware to go off be sure to let me know.

This is a great game!

It is only Version 1, but thats a good accomplishment for a game thats only Version 1!

When you will be adding Version 1.1 (or 2) Add a debug mode.

Hold on H for the plant finger guns.

Hold on N for the nukes.

Hold on V for vines.

Press F for pellets (NO SPEED UP and spammable.)

Press 2 for fast forward/speed up

Press M to spawn the green mouthball worms.

Press E to shoot 6 patterned star-shaped pellets.

Press R to shoot the non patterned bullet hell star shaped pellets.

Press D for the left flytrap attack.

Press F for the right flytrap attack.

Press A for the flamethrower attack to activate it and deactivate it,

And finally, Press S to save HP (vine, and star-shaped pellets also) And load HP. (vine, and star-shaped pellets also.)

You don't have to do this now, by the way.  You could do it later, or even a month, or even a year waiting. I would be grateful if you added a debug mode.

Also if you would add Debug Mode, make it so you have to be hit 666 or more times to activate it.

I beat this game on my 4th try. I'm so proud of my self!

I BEAT IT ON FIRST TRY HUMAN ON NORMAL MODE!

Well you are Papyrus the cool guy!

Woow ! It's hard ! xD

why is this taking so long to download THIS IS AMASING!

seriously though, why won't this download?

(+1)

This is probably the best Fangame for undertale!
So much effort is put into it!

I love this game <3

awsome

great job on this! this will forever be the BEST UNDERTALE FAN-GAME EVER

(+1)

Made A Video On It ;)   

You Should Make More Battles Like This! Also Game Is G R E AT ! :DD

(+1)(-1)

THAT IS SOME GOOD SHIT RIGHT THERE

(+1)

This is defenetly one of the best fangames out there, for me at least. Actually that's exactly what I wished for the original game. The original ps flowey may be insane already, but you just build what he lacked (especially the fact that it's 16:9 now)

Do you think you'll be able to port it for linux? I mean, thank god it's compatible with wine and despite the fact that when you die for the 3rd+ time the resume text isn't visible it still isn't that easy if it's not in the Itch library.

Also can you please add Y as an action key for the German layout.

Thanks for everything!
