Wouldn't it be really cool to get more objectives then just surviving and it would be quite useful if you get an extra upgrade point for a challenge. Here some examples:
- Speedrun Challenge: You will have to finish the level in a specific time, you can evaluate the time maybe by writing a code that counts the enemies and their average defeat time and summarizes the Result with just a few extra seconds and then puts up the timer in the level.
- No-Hit Challenge: You will face a hard level maybe with many bow-robots and try not getting hit by any arrows and that's the idea for this challenge just some ranged units in a small space.
3.Parkour Challenge: You will get two paths to choose, one is the parkour the other the normal level and if you kill maybe a garbage bot that waits at the end of the parkour you win the challenge.
These are just some ideas for challenges, these Challenges could really spice the Endless-mode up a bit and maybe in Twitch-mode the viewers get to vote on a challenge for the streamer. So this is the end of my post I hope you take this idea in consideration and thank you for reading!
