This might be the king of the twin stick shooters right now, in terms of the power fantasy this game provides.

Each capstone upgrade, aside from the less-bad-guys-line gave me a new stool to step up and marvel at my kingdom. Refining, time-per-shard, multiple shard-per-kill. Slowly I watched the cliff crumble and when finally it fell, the game felt great. The clock was now meaningless. I had won.

Or had I? I'm only going to drop one interesting thought here, and I hope it's one you know and agree with! In GMTK jam we, of course, have to try (and in my case fail) to make our games accessible to the average 2-3 minute playtime someone puts in. Often, like here, that means sacrificing the endgame experience to front load the action. Once I won, which was maybe six seven rounds in, all I had left to do was buy every upgrade, which just meant wiggling my mouse and keyboard to try to maximize my fragments-per-second under no duress or time. A little part of me hoped that after five minutes, there'd be some big dangerous boss, and all those hours of clock time I racked up would matter to my health, and when I beat him you'd come to my home, knock on my door, and tell me "congratulations son, you've won". As it's obviously not tuned to be an infinite game, I really think an ending screen, no matter how small, would have nailed this experience.

Now. It is fun. It is so so fun. At first I hated the diamonds, what a waste of left clicks. I tried to avoid reds so I could bunch them together and minimize the travel between their loot. I explored the tech tree, carefully avoiding some upgrades I thought were fillers to dig deep for the game changers. These are all top tier gameplay experiences. I can see you tuned the game to a fun average set of upgrades, and then gave us the option to have 20% more so we got to exerience overcoming your challenge. Intentional or not, it's kudos.

I think this is perfectly tuned for a GTMK Jam / demo. The second column of upgrades are all more interesting than the first, and upon reveal, you can preview and build your excitement for it. I had no issues with the controls, though, I never used the dash and the bomb only for farming massive times at the end. My inputs were responsive and snappy, and in my playtime I didn't encounter any bugs or even unfinished surfaces.

After the jam give me a big guy that spawns painful circles and makes me use up my two hours of clock! Love the work enjoy your day xx

Fun concept, captivating but needs a lot of balancing, you become overpowered quickly and enemies are not able to kill you at all. I don't get the purpose of upgrades that reduce spawn of enemies -  better would be upgrade that make enemies stronger and increase their spawn rate.. I 100% your game but around 80% of upgrades can be bought after just last quick run at the end when you earn 100k of those shards. The beginning of the game was was really cool tho and I enjoyed it. Good job and the graphics look really polished. 

Damn, This was so much fun. I love shoot em up for these jams, especially like these, So I loved it quite a bit.

And it is really well polished, everything feels finished. Well mostly everything.

Waves I think could have more variety, more enemies, more stuff on the map, faster upgrades.

I do like the idea of every move in game costing time, that was a cool mechanic, but that does restrict the gameplay a bit, so faster upgrades could help - I think upgrades could do with a rebalancing.

Apart from that, the overall game is nice, the movement feels nice same with shooting. And the upgrades are great as well(just prefer to have them faster).

I also do love that you have a working save system, that is impressive.

Overall this was so much fun. great work!

Super fun game! Very nodebuster-esque, and I could totally see this being a full game! I'd love to see more enemies and the game be difficult later game once the jam ends, and I'll be following this one!

A few small things if you do decide to update the game:

• I think refining also has the unintended consequence of multiplying time? Makes it pretty easy to survive infinitely pretty quickly
• The music seems to loop a little early
• You should add an end round button!

Still, these are all super small nitpicks, and this is still a great game overall!

This is a great game! The gameplay feels  well polished and satisfying, the enemies are well tuned and have a good variety, plus the gameplay is balanced great! I love the extra bit of challenge added by combining your ammo and health bar, it  makes you think before every shot in the early game.   The  enemies still feel like a threat while  not forming too unbeatable of hoards, which feels great early game, and the sheer amount of  upgrades you managed to put in game in just 4 days is impressive. I only wish that the hoards got bigger as you progressed through the game, maybe tie the amount spawned to your timer? It doesn't affect the enjoyment of the game, though, and is totally understandable considering the time restraint.   Ultimately, I think this game is crazy fun, and I spent a lot of time playing it! Fantastic work :)

One of my favorite games of the jam. I love how it starts as a careful economic game, but by the end you become so OP that money means nothing to you and you can just spam all your abilities. My only complaint is that the tech tree that reduces enemy spawns seems bad to me? If anything, I wanted more enemies!

Overall great job!
