Info
This is a tower defense game all about luck and extreme combos. You must apply skill and decision making to find the best towers to defend you against ever increasing waves of enemies! The game scales exponentially.
Each tower has a unique fire pattern and colour modifier. Each colour modifier applies a set effect to the tower no matter what it does. Some modifiers are better on other towers. (See below for guide)
You gain two gems for every wave you complete. You may choose to sell these gems at the store (press 1) or you may choose to hold on to them (press 2)
Controls
Click - shoot
WASD / arrow keys - move
Space - buy tower
Enter - sell tower
E - merge towers

Extra stuff:
For our fifth ludum dare we went back to our roots. The first game jam we ever did was a tower defense game, and it went terribly. But we're back and better than ever. Our team has grown in size by 2 and we have so much more experience. This was a super fun game jam to do even though we were a bit dead from university. Here's to many more Ludum Dares!
Explanation of some mechanics (skip if you want to go in blind):
The buying price of gems is randomized, but they occasionally are given value buffs.
Merging towers requires two of the same tower (colour effects do not matter) and it will combine into a random tower from the next tier. The colour effect of the new tower will always be the same as the tower that you pressed E on.
Colour effects give a random extra effect to the tower (as described below). Each tier of the tower will cause the colour buff to be stronger.
Selling a turret will give you 66% of the combined cost of the turret back. Selling is mostly used for finding the optimal colour for your build.

Tldr: This is a cool new twist on tower defense, but it could use some balancing/quality of life improvements. Nice game!
Fantastic Tower Defense here yes sir! :heart:
Some small things that I think would greatly improve the experience if quickly explained at some point:
- cost/benefit of holding onto diamonds
- cost/benefit of selling turrets
- how the merging mechanic works
Anyway, this game is definitely among the top games I've played this LD!
Although the later levels are very similar
Nonetheless it was also very fun
I made a fortune on level 19, the two orange gatlings were very powerful

I ended up here. Really fun, the gatling does very high damage, far more than the other towers, I guess I should have added more towers that slow down the enemy. All in all a very fun game!

I thought it was a funny thing to see moles umbrella-ing down to my cart because they too burrow down deep into the earth.
What I did not understand at first was what I was buying to begin with while walking the shop the first time. Maybe explaining that each arch on the descending platform stood for a place you could purchase a particular gun. Besides that, I really liked this game. Keep it up :)
But the graphics and gameplay are pretty good with good polish like the gun smoothing.
