Run of Valor

I really like the stamina system, but I think it should be used not as a clock but as a turn counter. Maybe instead of losing stamina based on time you would lose it based on how many attacks you do or how many attacks you block. Then, you could add more debuffs like fatigue, which makes you lose more stamina per attack.

Also, the enemies should scale more exponentially instead of linearly, as the game doesn't increase in difficulty after the 5th stage

Other than that, great game!

As a proof of concept this is fine. It has potential. I suggest adding some kind of game speed up (skill or a relic e.g. speeds up movement and attack speed by x%). Also currently there's only 2 relics worth upgrading, protection and necklace.

Both speed up the game, since you either need less hits to kill an enemy or don't get stunlocked for 10 seconds

You can upgrade vampire, but I don't see a point to upgrade it past like 5%-8% since it will matter only on the first lap. After that you start scaling your stats faster than enemies. 

Power is completely useless since it only affects starting damage and does not scale. 

While endurance is the only way to rise max hp its far more beneficial to spend those gems on more money and buy defence to negate damage.

Your quest are a bit off, I think you accidentally set distances in meters instead of centimeters, at the point you can realistically think about grinding 100km cumulative you probably have all the upgrades you need to play indefinitely, if you wanted to. At that point getting 20 gems for your effort feels more like a slap with a dirty rag than a reward. Same goes for other distance quests. 1000m would be far more realistic and the reward reasonable.

You should add some sort of automation to this, since it starts to get annoying to buy same 7 upgrades every 3 enemies and it just adds unnecessary mouse clicks.

Potentially some sort of prestige mechanic would be an interesting addition.

I just wanted to say that after a certain point you are able to always buy everything from the store each time and you will never lose. I have all 5 relics decently upgraded but as the user below me says, even in this state of "invincibility", I'll never reach the distance quests, too much manual clicking involved and too much time needed. 

Otherwise, great graphics, great feeling of the game, great stuff! 

After the first few runs a lot of clicks are needed at the store. There should be an auto buy option, especially if you're setting your Quests at 100k M. Non-robot people will never hit that. I know this is a demo but I just spent a few hours repetitively buying because I was sure there had to be something on the other end of the rainbow with the quest distance being that high.

Have u tried making it into TG game and making money this way?

Nice game and art. I just played few runs, but if I were looking for any game to play, definitely would play it for longer.

About monetization - have you thought about adding this game to sites where you can add ADs between runs for like +1 gem?

Feels like a de-make of Stickman Fight.

Great looking game, good luck! Do you have a plan for gathering audience, or/and monetizing the game somehow? This type of game would be something i would immerse into.
