I like this game. Bright, fast, fluid and fun. I really enjoyed this
Some feedback and opinions:
- I really wish there was some limited alternative weapon, say a grenade, that could take out multiple enemies.
- Differentiate the speed between mobs. It was too easy to round them up into a ball and kill them.
- Upgrades use score value, and the measure of the game is the length of survival, I would use another name, "score", which gives a misleading impression as it is really a resource. The true score in the game is the length of survival.
