It's so close to being awesome, only a few more days in the oven and it would've been done. There are a few minor tweaks that would make it play much better to me:
- smaller player collider, it's really hard to fit between bullets, I'd go for 50% of what the player sprite is actually,
- a few very short and much simpler levels to start,
- shooting is not really needed and it doen't have a purpose atm, I'd remove it,
- audio could make a big difference :)
Would play again, I'll follow the development ;d
