I don't have time to write out a real review, but I did stream your game here:

 Your game is really good, maybe is a little bit hard but I have fun.

Ok I had to rewrite it all over again since my computer crashed.

I have played it for about 25-30 minutes. 

It started out real slow for me. I guess you ramp up the difficulty based on how many pick ups you get, but I kept getting the pick up from the enemy which was right at the bottom of the screen. Happened to me for like 4-5 times in a row. And since you take a lot of time to kill enemies in the start it was slow.

After I started picking up the power ups (and also avoiding killing them when they are at the bottom) it took only one minute for me to be a god of destruction. 

I don't know what is the limit of the pick ups but I guess I was well over the limit. At this point it wasn't difficult at all. I just played to see what's more.

Overall I enjoyed it. 30 minutes of playtime for a jam is a lot. I think I would want it to be more fast in the beginning and more difficult at the endgame.

Well done!

Love the game, the art and music are mu favourites, LOVE IT!

Hey dude! Your game is really good, i like it! :D, maybe is a little bit hard but I have fun!

The game is pretty good, everything is well put together, the only issue that I feel is that difficulty varies widly, from having collected 3 Powerups or only having 2 abilities to combat with 8 enemies at once and more enemies were keep appearing on top of that, up to having nothing to shoot for a while even though you have all the abilities and collected around 11 Powerups. You should rework the difficulty, like how many enemies are appearing, on how many powerups have appeared and healthpacks. And maybe you can add new type of enemies or bosses but overall great game, I had a fun experience with it.

for security reasons i cant play your game on my mac but all game developers start small and rise higher than they never gone don't take no comments for the reason that know one wants to play your game be proud that you managed to upload it and make a full game for people to play well done
