I really wish there was a meh option for reviews, because this isn't really a yes or no kind of game. Despite my playtime on steam, I have played this a bit on mobile, and so this review will be largely focused on the overall mechanics and progression of the game, as opposed to the port itself.
To jump right in, Monolisk is a game split into two core modes, the ARPG dungeon crawling hack and slash, and the level builder, both with their own Pros and Cons.
On the ARPG side, you have a fairly simplistic top down hack and slash with 5 classes to choose from, and 4 possible skills equipped at any time. Then based off the level of your gear and hero themselves, you can tackle levels made by other players to accrue small amounts of currency and exp. With this stream of never ending player generated content, you have a much wider range of stages that go far beyond a random level generator, but likewise, that also means many levels aren't professionally made, so you trade craftsmanship for variety.
The big problem arises with how the game handles loot however, you know, that thing that ARPGs live and die by. For in Monolisk, loot from dungeon crawling, isn't really a thing. Instead of monsters dropping any kind of usable or interesting items, they drop that aforementioned currency, in very small amounts. The actual total in each stage is based off the average clear time, and can range from 1-30. With this currency you can buy packs of cards for 1000, which contain 5 random cards. These cards could be useful gear to you, or they could be trash that you dust. With said dust, you can craft any card you want, but the ratios are absurd as it can take months of dusting cards to make a desired set. If that sounds unrewarding to you, it's because it very much is. Now once a day you do get a random daily quest, which can stack up to 3, and these can give 500-600 currency each, which means it's far more rewarding to play the game for 10 minutes every 3 days, than it is to play for several hours. This in itself kills any sense of that traditional ARPG Progression, but if you have a very limited amount time to play games, it can be nice.
Now on to the level making portion of the game, which you would think the developers would really want to go all out on since this is what people will be engaging with most, both as dungeon crawlers and builders! However, that's not really the case as the CCG Gacha aspect of the game becomes its biggest downfall in this mode. For you see, to make a level, you require a map, a shard, which determines the size limit of a map, and the monsters themselves. And while the monsters can be used repeatedly on all your maps, the maps and shards themselves are one time use, and colour coded, so if you pull a green map, and a red shard, they don't work together, for no real reason outside bad monetization.
What this means in actual practice, is as a level maker you're extremely limited with what you can actually make, and have to either throw literal hundreds of dollars at the game, or grind dailies for months before you can really start to make some interesting maps. Oh, and those dailies are all for the dungeon crawling side, so I hope you're not only here to make levels, because you get very little reward for even making them. Eventually, IF enough people play and rate your maps well, you'll occasionally get a pack from it, but these are extremely few and far between.
As for the actual process of making said maps, you can place ground, furnishings, and monsters on a large tile based grid. You can get a bit creative in design, but there's almost no mechanical depth at all beyond place monster here or there. No delayed spawners, triggers, or patrol routes of any kind, just static monsters placed in one spot until aggroed. With the very very few things like portals and key doors, locked behind very rare map cards, that cost weeks worth of dust to craft a single copy of. You can also place signs with custom text, and link maps together in a campaign to create a pseudo storyline, but without any kind of NPC system, it feels very oddly fake. Like a ludonarrative scenario that you have to buy into with imagination, as opposed to the level itself feeling like the thing it claims to be.
Overall though, despite the complaints, what is here is made competently and has a nice layer of polish for an indie game. The developers themselves are also worth praising as they are friendly and active on the discord. I do not personally believe the poor monetization is done out of malice or sheer greed, but it does inadvertently ruin the game. This is just one of those games that would have been so much better off being a 1 time purchase with DLC, as the CCG Gacha kills the joy of ARPG progression, and dramatically limits your tool kit as a level maker. There are just better games in both genres that are so much more respectful of your time and money, but at the end of the day, it's not the worst of its kind either.
