Great game

I love this game, I have been playing it for about 6 months. The developer is very active and adding new content. It seems like it’s a small team so new content isn’t necessary 100% perfect but it’s still great. I usually quit hero collectors after 3-4 weeks, it’s the perfect mix of hero collector with idle defense.

One comment to developers: there are lots of stats to consider in the game and there are limited tool tips about what the stats do. For example: My +Crit chance is 3327, what does that mean? Is it an extra 3% chance to crit or something worse?. More transparency on character stats would help make team and equipment decisions more informed.

Well polished game, limited decision making

Everything in this game looks great and feels great to play. The monetization is mostly ads that feel non-intrusive, the real world transaction shop is so inefficient it prices out everyone but whales, and they give you an option to opt out of all ads with a one time purchase, which I would recommend for anyone enjoying this game.

That said, this game suffers from a big problem: there aren’t any meaningful decisions being made in team composition.

Essentially, you just want to put out your best heroes at all times to maximize damage out and minimize damage in. The combination of heroes does not matter, because they don’t interact except in the minor debuffs on enemy monsters. Even in the Portal which debuffs your types of damage or mitigation is irrelevant; optimizing for the challenge might push you forward one level, but the reward is so small compared to just maintaining and waiting for your other stats to get there. I feel like this can be partially fixed by providing meaningful buffs based on the number of heroes of each “class” deployed (archer, warrior, wizard, whatever) or some other commonality, which would encourage mixing and matching of heroes, make the non S/A tier heroes less useless, and give this game a little depth.

I’d still recommend this game to anyone interested. The game is still beautiful, the developers appear motivated and progression feels exciting, albeit a bit unimaginative.

Game is great but one FATAL flaw

Love the game. Thoroughly enjoying it even as free to play, however- there is one MASSIVE flaw which prevents me from spending a cent on it; the “targeting system” or lack there of. Your units will literally walk right past a boss (sometimes multiple times) that’s directly attacking the castle to attack a single unit with 2 hits left, etc. it is an absolute mess. There is no way to prioritize or customize targets as in most tower defense games, i.e. closest to tower, highest hp, etc. you will fail countless missions you have more than enough firepower to complete because your units wander around aimlessly (castle archers are equally as worthless). You may be lucky in getting an AOE unit to aggro the boss but it’s few and far between. Other than that- which is major problem, is a good game.
