This was really fun, although I didn't play to the end. This is probably something that you considered but didn't have time to implement, but I feel like the low ammo capacity (even after upgrading to eight shots) kept me running back and forth over long distances more than was interesting. Maybe offer a slow recharge while not moving as an upgrade?

Just letting you know that the Mac version of your game doesn't work (therefore did not rate your game). I was keen to try your game as it looks like you've made great use of the tilesheet.

Amazing game! Shop prices feel like they need a little balancing. Also, geared up to go fight my first nest and found out you don't keep your inventory when your ship respawns. Will definitely be trying to beat this one later! I love it!
