Starts off quite slowly but the difficulty ramps up pretty quickly.
A few suggestions:
- Make the enemies with more health bigger than the small enemies
- Make enemies it more clear when an enemy is fully dead
- Would be nice to see the laser cooldown close to where I'm shooting, so I can think better about when to shoot. Now I have to look in the top left corner, diverting my eyes from where I want to shoot
- Make the difficulty go up small steps at a time
- Make it more clear that I can purchase upgrades, didn't realize this until a few plays in
Overall, a nice game!
