WEll done! Fun game! 

Tho I didn't fully understand how and when ammo ran out, so it would be a nice touch to let the player know about the ammo.

Otherwise a very well done and polished game! :D

The design is simple and effective: while maintaining minimal art, I enjoyed the presence of key animations (enemy death, grabbing items), since they make the game modern despite keeping a retro feel.

Also good choice in making a boss appear sometimes, as it adds a little variety and poses a challenge.

If I may suggest some feedback, I would add multiple enemy types (slower, faster ones) and give the boss a little feedback on the fact it has been hit (such as small particles), but overall it was a great job, the game worked and I haven't encountered any bugs (got to a high score of 178)

Thanks for the submission, all the best! :)

Fun game ! Not sure to fully understand why i can't shoot sometimes ? Looks like an ammo limitation.

Feel good to play! The audio is simple but adds a lot. I had some horrible lag spikes on web on like every third kill, but on the downloadable version it was fine. I noticed there is some kind of ammo system, cause sometimes I can't shoot, I just wished this ammo was clearly communicated to the player so I knew how to "save" it more effectively.

Fun game with tight controls. Well done!
