Devlog: Level 1 and new wave type "Burst Wave"

Work on Level 1 and more features

I initially started to work on an endless mode before level 1. But halfway through development, I realized that it requires a lot more time than I intended and is a little bit too technical for me. I then rolled back to working on level 1 since the tutorial wasn't really any hard or had much to do.

Level 1 will feature the following new additions:

• Better designed waves: The waves actually make a lot more sense now, on how difficult they are and how the rewards at the end of the wave connects to the next one.
• Burst waves: Rather than spawning enemies with a constant gap, this level will also have burst waves, which spawns several enemies at a time in bursts.
• Tower upgrades: I'll be working on the first ever tower upgrade for the first tower, the Sentry (I'll also be working on passive upgrading for towers. But this isn't confirmed yet for the next update).
• New enemy: There will be a new tougher enemy in this level. An upgraded sentry is really gonna help on this one.

For the next update, I will also try to implement a better tower targeting system since the current one sucks (it targets enemies closest to the base IRRESPECTIVE to the path).
