With the embed resolution fixed, the game is now perfectly playable! It's a decent tower defense game, but I would like to see more tower options, and perhaps a variety of levels. Overall, a pretty enjoyable experience

***Updated and now able to play***

Not sure if I can actually 'Stop' the march, but it is a fun little take on a defense game. The big open grid presents a lot of strategy problems for us to solve.

1) Would be nice to see HP gauges on at least our towers and fences since they can quite easily be destroyed. I thought they had an HP gauge on them, but they appear to be losing HP even when there are no enemies around, so not sure if it's a timer, ammo, or HP. Although the difficulty of this game is hard enough without having to compound limited ammo or degrading HP into it.
2) I sort of assume how much gold I have based on what's highlighting. It would be nice to have a static counter
3) I don't think the power/hp ratio of the towers to enemies works. It doesn't seem like a "next tier" tower has that much more HP or defense than the previous towers, and you're visually showing different types of firing sprays that "seem" like they should have splash damage but don't
4) Tower seem to basically have the same HP, which slightly higher damage, but less range than the t1 gun.

This game has a lot of potential. In it's current iteration it's an unbeatable single level "endless mode" I didn't exhaust every strategy, but my longest run right now is 103 seconds after 20 minutes. The degrading HP in correspondence with the ever increasing enemy counts gives the whole game a sort of "last stand of the Alamo" feeling, which for me takes away a lot from this game. Since we don't get gold from killing enemies, we can't horde towers to a small corner of houses to focus defenses. And we've basically got a fixed Gold cap of a few hundred gold, and since towers can die from enemies also that gold cap is constantly degrading. Let us stop the March!!!

I'd recommend the towers get a mouseover or tooltip description, and give them appropriate upgrades, if t3 tower has splash damage, maybe it's ok to have 3/4 the range of a t1 tower, because it does 2x damage + splash, t4 tower seems like it should at least 2x it's current range which is shorter than t1 tower atm. T2 tower should be at least as strong as t1 tower in terms of speed and power.

I know it's hard to program, but if you expand this game out, possibility of letting us focus enemy priority. This lets us develop better strategies.

Fences are basically money down the drain since towers are still taking degradation damage.

Maybe the whole game needs to shift where you have 4 clearly distinct types of towers + fence that we can upgrade. You visually have distinguished your towers, but the actually effect is still 1 target with limited range and fire speed. Tweak the costs, and tweak the effects. Big wait yield big rewards.

It's fun for what it is. But it could be so much more if it was planned out for longer runs. Possibly bosses. Possibly beatable scenarios with more levels, etc. I think the tower degradation could be removed completely, OR we need bonus gold from enemies to help us scale, or both.

Looking forward to see how the handle the current 2 minute game length cap :)

Looks like a nice game but how do I place towers?
Ah, seems like the resolution isn't big enough to show the UI on the right. Be sure to update the Project settings.

Edit: Cool game, good job!
Nothing beats several rows of weak turrets, just keep in mind that repairs are free!
