I think I got the enemy counter bug at the end of the second level. Still some cool concepts here. It feels clever to have you take damage when the controlled ship dies because you can't just kamikaze everything. But that probably needs a little more cleaning up or tuning. Especially at the start of a level, there's so much going on that I couldn't find a safe ship to grab and ended up dying immediately after taking something.
Also, this game could definitely use WASD/arrow controls. The move-to-mouse works in some games, but when you have to use the same controls to aim and take control of enemies, too, it can be a little unintuitive.
Overall, great job on this. Well done in 48 hours!
