The game is an excellent puzzle game, everything has been said.

However, I do want to make people aware of one thing that really rubs be the wrong way. A big selling point for the game is the extra user-created content, it's right there under "Over 25,000 usermade rooms available for download!". I finished Gunthro and have been looking for some of those to play, and.... I effectively cannot play a single one of them, it seems. Even the most recommended ones, those that are mentioned in discussions of what Levels to play first, require knowledge that the game just has not taught me at all. Decoys, Mimics, Spike Traps, Potions, Tokens - none of these things are part of the game I played.

It seems very clear that what you're expected to do is to buy and play every single DLC first before you can properly enjoy the free user created content, and that should probably be mentioned somewhere.

Even more so, there seems to be a Mod made for Gunthro, specifically, called Flood Warning. Except you can't download it for free and the most recent information that I found on it is a 3.5 years old forum post indicating that it does not work with the steam version and people will have to wait for it to be released on steam, except it apparently hasn't yet. (source: https://steamhost.cn/steamcommunity_com/app/314330/discussions/0/350542683196964995/ )

I even tried making a caraval account, but apparently the only way to register a game that I bought from this developer with their external service that is also advertised in the product description is to buy the game again directly via their external site. Additionally, to use the, again, advertised high score system, I would need to buy a subscription with caraval for only 12€ a year! That is NOT what is to be understood under "Hi-score competition and hints system via our CaravelNet service"
None of this is okay. So at this point, I can't access their score system, I can't access the otherwise free Mod Flood Warning, and I can't really enjoy most of the free user created levels because they require knowledge that is not taught in the base game they technically belong to, but in the multitude of extra purchasable DLC.

At this point I can't leave a positive review, sorry. The advertisement for these features are just completely misleading.
