Even though the game is unfinished, this could be a great casual game if you make the point system balanced. Here's a few ideas:
- Maybe you could make the level vertical so you can spread the enemies out way more (spending points could make the level longer so it becomes harder)
- Maybe you could make it so that the player can also earn points during the game instead of having a fixed amount.
- Currently there's not really a reason to not spend all of your points (but there could be a ton of ways to fix this)
Again, cool project and good job!
