Comments on Undercity for Android

★★★★☆ Timesup · Aug 29, 2025
So far actually quite nice! Many complaints about the stop to attack mechanic, but it's chosen to make it challenging. I've played other popular survival type games with the same mechanic. It's adaptable. I love the art style! Hopefully lots of equipment and pet content!! No forced ads, only for rewards! So far so good! Let's see some events, other playable characters, and some other game modes, and you are on your way to a winner dev! (keep everything fair for free players please).
★★★★☆ Spawn · Oct 20, 2025
I love this game🤗 But. 🤔 The only problem is that 9/10 times there's the option to watch ads (Basically anywhere you see that you can watch ads!) the ads won't load so when it comes back to the game you'll be stuck on a black screen with the game music still playing in the background... All you can do now is close the game and reopen it...😮‍💨 And you can only re-enter the dungeon you were just playing once! So if you get the black screen twice then you'll need to restart the whole dungeon
★★★★★ David C · Oct 27, 2025
Great game so far. I really like the game play, the movement is very good, and the combat system is a lot of fun.
★★☆☆☆ Zero Eggnog · Jul 28, 2025
Why it is worse than (clean earth) can't attack when moving is big minus with swarm of enemies/boss picking you at range
★☆☆☆☆ Branden Niblett · Jun 23, 2025
"You can't attack while moving ". A bunch of nonsense
★★☆☆☆ Xavier Velasquaz · Jul 15, 2026
don't care how cute, ads messed it up. Not even original or complex game development why you need to pay to play bs $5 to just play a game uninterrupted is retarded might as well just get console if i want to be beaten out of pocket
★☆☆☆☆ Darksahde · Aug 25, 2025
Hit a wall at stage 17, paid the ads pack and the welcome pack pro: great artwork, monster collection is fun and unique. Cons: The first wave in a stage is way too hard for level 1 monsters and Mc alone. No chance to upgrade equipment does too little. The configuration seems to want you to use different monsters in your group, but it's actually better to spam multiple copies of the same monster. Music/sound effects is so bad it's a nuisance rather than enjoyable.
★☆☆☆☆ Daniel Stoneman · Nov 30, 2025
I actually like the game, but the ads that never end are beyond frustrating. Not all ads do it, but occasionally I get stuck in an ad I chose to watch for a reward, but after MINUTES I'm not given the multiple "x" icons needed to exit the ad back to the game to get the reward. Reboot app, lose effort and time, no reward. Fix this. So far it's mostly been monopoly go ads.
