Thanks for the support and feedback! About the stats change, yes that was intentional. I recently went and tried some free-to-play tower defense games for a matter of reasons, and discovered this concept was actually pretty used, but in the poorest way possible. Just one tower, you mix it again and again until it's OP, done. That's boring, it's like grinding but you have to do it each run. By mixing the towers you got available, I discovered you could actually interpret differently how the boosts will work. Scout + Soldier gives you a firerate boost for the Scout, while Soldier + Scout gives you a damage boost for the Soldier. Which is better? It depends. Cost is the same so you mostly have to focus on strategy.
I really wanted to make a neat game, try to bring something new, but actually found it's not that hard to re-imagine and ol' boring concept and actually make it enjoyable.
About the tower placement, I didn't know that happened. Probably is because of either the lag or some other things.
Sadly this project will take a while to be developed since I ran out of events in Construct 2, but I'm trying my best to get it done on Unity so I can continue to explore the potential of the idea.
Locking the mouse is also an idea I had but I'm not so sure about if it would be benefitial or not. What I enjoy most about Tower Defense Games, is the challenge that you get when you are just starting to play, which gets lost mid-level if you already have a good setup. I think the main problem with this demo is the firerate boost, which basically allows you to AFK. Don't get me wrong, I like afk-ing but I think too much of it and the game becomes an animation that's longer that it should be. Also since I see both you and a friend that tried this game liked the change to lasers (which was unintentional lol), I probably will try to make lasers return in the completed version, just in a different way to avoid that much lag.
If you read till here, thank you. You actually gave me the main idea for the project and I really appreciate your help. Wether is it Unity, Ct.js or any engine you can imagine, I promise a fuller version of this will definitely arrive.
