Spoilers: During the fight against Sans I encountered a bug/glitch where I was put on the cieling and I couldn't jump when I was supposed to be put on the floor. This also caused me to lose and die.

Hi Toby! I encountered a uh, kinda serious bug. *Note- Spoilers Ahoy!*

So, I am playing the Asriel boss fight, and when I got to the SAVE section, I was playing as normally, but Alphys' soul's name was yellow. I attempted to spare her, which turned her sprite into a spared Aaron, "winning" the battle and depositing me in the Barrier, (Which, I noticed, ironically, you programmed no barriers for.) still allowing me to walk around. SAVE The World plays endlessly in the background. Is this my personal hell for my sins?

EDIT: This bug hasn't stopped me from resetting to my save and playing again, so I guess it's kinda minor

birdish-nerdish: WOOOOOAAAAAHHHH that isn't good LOL and you didnt hack your save file or anything like that?

again anyone who cant run it or has a file destroyed email me

In a pacifist run, during the first form of Asriel boss fight, sometimes dying will stop all dialogue. Without any progression of dialogue, the entire fight is endless and unbeatable. The only thing that fixed it was restarting the game

This isn't directly related to the full version of the game, but I'm wondering what's wrong with the demo? I'm afraid to buy games without first trying them to see if they like my PC, and this thing is *slow*. 60-80% CPU usage on average. I play 3D games that are less demanding.

My friends reassure me the demo wasn't optimized, and the full game runs much better, (Averages at 15-16%; much cooler.) but if that's the case, why isn't it up to date with the full version?

It's leaving a bad impression on me, since Freedom Planet's devs were kind enough to update their demos any time there was a stat/move change with Lilac or Carol, so they could get feedback on the combat outside of the Kickstarter backer community. (I bought it on GoG instead of Steam, if anyone checks on my library.)

I'm not suggesting the demo has to be updated infrequently, but anything's better than letting it cook unwary potential customers' computers.

I really love Undertale's atmosphere, characters, and music; I seriously want to buy this game and play it. I just can't do that unless I know a proper, updated demo cooperates with my PC first.

Idk if this counts as a game bug or a Steam bug or what, but it seems like my play time reset? When I completed the game the first and only time, I clocked out at about 8 hours. Since rebooting the game and getting the message about resetting and subsequently quitting the game again, my play time has been bumped down to 110 minutes.

Any idea why?

[Admiral Hamfist]

During a pacifist run I didn't get judged by Sans. This was the second run I've done overall with my first being a neutral run. I reset in-between the two. The second run worked properly as a pacifist run as I saw the true lab and got the true ending, just no being judged by Sans, which I was hoping for because I wanted to get his key and see what the deal was with him.

Other things of note:
-The whole area after exiting the true lab was gray & had no music up until meeting ASGORE
-My first playthough I killed Toriel and Flowey, but that didn't effect anything else

[LightningSonic]

So uh, I have a bit of an issue.

I can't seem to be able to move in a diagonal direction, with the exception of being able to move towards the bottom left.

This makes it way harder for certain sections, as I'm really only able to move up. down. left and right.

Spoilers: Yet another glitch I have encountered during the Sans boss fight. I was healing before his final attack and when I healed one of the menu bones (which are tottaly fair) stayed on the screen where my cursor was and took all the hp away that I just healed. This is yet again another glitch that has PREVENTED me from beating the game. I am starting get pissed with glitches causing me to lose to Sans which is already an unfair boss.

Oh... never mind...

Edit: The game crashes if you fullscreen on the final boss

I also have this Problem

[Xephoriah]

I'm having a bunch of graphical glitches, the text boxes flash and some of the textures in the game are glitched out and show a bunch of colors! pls help!

[spenscat]

During the Metatton boss fight, while they were in EX form, I shot and destroyed EX's heart during the sequence before EX is supposed to lose their legs, and the game crashed with a dialogue that, if I recall, said something like "error... Metatton_Boss not found". I reloaded the game and it was as if I had lost to Metatton. This was my first time battling them.

[Cherry Bun~]

Deep into the Sans battle(read, Last 5-6 dialogs), If you are slammed twice against the same wall when the bones are popping up in rapid succession, you will get hit by the bones that have not yet disappeared back into the wall

Sometimes my save data gets deleted

[smol excitable birb™]

Early on in the game, just before/during confronting Toriel, I had an issue with the music (but more so the sound effects) where certain sound bites would loop and clash with the music. Leaving the room and returning seems to fix it, but I thought I should post about it here as it's happened a few times in other areas too. Could just be me, though!
