Made it to level 12!  I had a fun time with this one even if it gets a bit repetitive after a while and the only real difficulty scaling is the addition of more planes.  Maybe something to expand on is the addition of new plane types that fire differently or ground turrets that target the air.

I'd say my biggest complaint is the lack of a health bar.  It's hard to gauge how careful I need to be about getting attacked without any idea how close I am to exploding.  I noticed after reading some of the other comments that the smoke color changes, but I don't know if it's apparent enough to warrant no health bar.

Besides that, I will say that the little arrow indicators for the artifact positions are very well done and super helpful!

Also cool to see how someone else used the same tileset in their entry :)

Great visuals and very polished game!

That was a very nice and polished game! There was just a tiny little problem. I think the game was very easy. But except for that I liked it very much! Well done!

Fun game. I really appreciate the arrows pointing you to the artifacts, and I liked saying "It belongs in a museum!" every time I collected something. Would have been nice to have like a life bar or something other than the indicator smoke.

This is a totally reasonable number of planes to have in the air at one time..

Relaxing polished game. ^^

Great game! Love the concept, i would only suggest to make the mapp loop when you rteach the end, otherwise AI just traps you in a corner and kills you haha, feels a bit unfair

Cool entry. I like the feedback when you destroy the enemies. But this feedback could be applied on hit in similar fashion. At first I thought I would not hit the enemies at all :D.
Anyway nice visuals and the audio is also nice. Good job!

good visual and nice idea

Got sucked into playing quite a few levels. Clean visuals, and smooth gameplay. Nice job!

Wow! Cool ideas. Your game is fun.

This game feels really nice to play! My favourite I've played of the jam so far :)
