So good game, but can you please add lust sans to the game? I've always wanted to do the anxiety sans fight aside from that, it is one of my favorite games other than undertake and delta rune.🤎🧡💛💚💙💜

It's a super cool game, one of the best Undertake fan apps I have ever played. Some issues I had were the controls not moving where they were supposed to. I put that I wanted them on the right side of the screen, but it ended up on the left anyway, plus it wouldn't let me move it to the other side in the customization menu. That's really the only problem I had. I can't wait for another update and more battles! Maybe we will get OG Swap tale Papyrus or a normal Sans fight.

Alright time to rewrite what my previous review was, the movement is actually janky I can't spin superfast like I can in other apps, also why isn't there a 'hacker mode' where you can mod (like your heath)also I had it on 30 fps, and I could run higher than that but the fact that I tried to actually see if it was me when it wasn't is crazy, but I hope this game gets better. Until then, it's just going to rot in my phone until an update sorry dev but your games. Movement really is bad

The battles are pretty good, but they are extremely difficult to maneuver. And I like that the naming works the same as Undertake, like with Chara being the true name, and other characters' names not being allowed. HOWEVER! Gaster crashing the game is completely understandable (as it does that in Undertake & Delta rune), but River also crashes it!! IDK if it's a bug, a glitch or just some AU's rule, but please get rid of it. Thank you.

Overall, when I install the game, random games get installed onto my phone, and the developer seems like the concept of respect is unseen, judging by these replies, other than that, good. (Add revenge the unseen ending, and I'll make this 5 star-)
