Lots of fun and nice upgrade system!

Great game there! I had fun! Voted! :)

I love when the game mechanics are simple yet lead to a fun experience. The progression is nice and accompanied by a cute and well-made art and sound design.

As others have mentioned, some different content would be great to make things more interesting and less repetitive such as more upgrades, moves and obstacles/ways to lose hearts. But it is a jam game of course! :)

The game is really fun and the transition too the game from the intro is just awesome, how the music chances and the water starts coming down is very epic, and the way how you get one firefly at the start, and the second gives you the second one to instantly get an upgrade, to teach that mechanic is pretty awesome.

The game does get pretty repetitive after a while, so maybe some alternate obstacle thingys, like bombs that explode after a while in a 3x3 area and stuff like that.

Them the harsh black outlines on the spikes look pretty bad, maybe a lighter gray would look better, because they look kinda weird on the light ground.

Then the firefly amount for the upgrades scales way too quickly, you should make it scale faster in the beginning and slower in the end, so max you'l ever need for a upgrade would be about 12 or something. But keep the 2 fireflies for first though, it teaches the mechanic really well.

Very fun game and very addicting to keep playing. I really like the upgrade loop of the the game too. Graphics and audio were also well made. Nice work :)

Funny game and interesting concept)

Really nice game! Loved the animations and sounds

got to 17k! really engaging, I love the mechanic of the little upgrades every time. But they got less frequent pretty quickly. Wouldn't have minded some more chances, and more different types of upgrades

Fun little arcade style game!

Really enjoyed playing this game! When the spikes started to come up in pattern formations, it was such a fun rush to avoid them and keep collecting! Animation is cute, and the overall style fits together well, nice job!

Was a fun game to play and simple to learn. Enjoyed the experience! 

Very interesting game, could be a good time waster if there was more content!!

Would make an amazing mobile game with more content! I enjoyed.

Fun, pretty, maybe a bit slow difficulty curve, but overall great.

The gameplay is a bit simple, also it is a bit easy at first but it soon gets challenging. My best record in 14000. I realy like the graphic of this game. The art is very cute and the animation is neat. Good job!

Also, if you have time, please take a look at my game, thank you.

Funny and therefore interesting

What I think does it for me is  the graphics. So simple yet so good

Honestly such a well made and polished game. Good use of the powerups and great replayability also all the art sfx and music worked well to create a great look to the game. Well done had  alot of fun 

Great amount of polish and game feel. Sound effects are perfect choices, simple but fun! Nice work!
