Yeah I released an update few weeks after the jam to polish the game and expanding it, so I made the skill tree despite the fact I absolutely HATE UI design/programming, but that was an opportunity to learn and to practice (yeah the interpolated mouse is not the best idea, especially that it's frame rate dependent)
If you have reached the wave 50, we can say you beat the game, cause all the waves passing this cap are exactly the same.
Currently the waves system and the economy are a mess, made with 0 mathematics consideration. So I need to make a proper infinite dynamic wave system, both challenging and fun with a good difficulty curve. I want the player to loose at some point, cause for now there are nothing to counter the lvl max player's death machine, so yeah, we need an endgame, a score, an ending, something, I don't know.
The "???" is for the work in progress and for a mysterious 3rd character class :) fun fact: you can actually "buy" the "???" for 9 999 999 coins.
Oh and I guess the camera shake is okay now, you didn't mention any earthquake :)
