I liked it, it was quite polished and the game feel was great. You chose to use the rewind as the "panic bomb" button that is present in many Shmups, and I think it's actually more interesting than what is typically done, it requires more skill. It does lend itself to a short play time, as there isn't that much variation. But it's great for a jam game :).

My only request: show what the "rewind" button is only after the first time the player collects enough energy! The game shows which button to press (right mouse button) right when the game starts. By the time I got enough energy to use it I had already forgotten what it was! Since you cannot immediately use it it's harder to memorize the input.

Overall: good job!

I had a lot of fun with this game. I couldn't exactly tell what the powerups i picked up did. And if you added a score system and powerups this game would be really really fun. It was a lot of fun to play. If you were to take this game further I would recommend evolving music that gets more intense as the game goes on, but for a game jam this game is wonderful. Thanks

Really fun game with smooth controls! I had a lot of fun blasting the enemies and dodging them. I have two improvements that you could make tho - one is that for the weapon upgrades, you could increase the number of bullets you shoot per shot as you get more upgrades to make it more visually satisfying. I'm assuming right now it just upgrades damage, which doesn't really seem to do much because I one-hit all the enemies anyways. The second is add a sound indicator, like a beep, for when you get full energy so that you don't have to constantly look down at the bar. Overall, great job!

Super fun game to play. The movement and controls were all really smooth which felt great

Shooting and killing are very satisfying thanks to the sound effects. The only issue I really found was the instructions on how to play. My first time playing I was more concerned with surviving and shooting so the text went mostly ignored, then my second play when I felt more comfortable with the flow of the game I read and understood them. After that they just kind of got in the way. I think you did a good job of presenting them in a cool way, it's just that maybe it should only be on your first playthrough and it should pause and let you read it.

A really fun game that feels good to play nonetheless, good job!

Really fun, I like the dynamic and high frame rate, shooting feels fun, maybe lower the sound when you loose is a little too high and I got  scared,

great game 

Good theme submission with asteroids, really fun game! The result is solid which is something extra for me when rating! Great work!

I would really appreciate your opinion on mine as well if you have a moment.

This is like asteroids on crack! Great submission! Meshed will with the theme.

Please play and rate my game as well!

This is a really simple but fun game. The audio paces well with the gameplay. Though I wished there's stuff like health points and more powerups instead of instant dying. Nonetheless, pretty neat design!

Awesome game, simple but extremely fun, one of the most fun games I've played in this jam in fact!

I agree with @Solo Byte Games, it might have been better to let the rewind ability be used with a partially full energy bar, for example a small rewind for each "chunk" of energy.
