The game is good, the gameplay is okay; it could do with some more work like more upgrades. The arts is good with the screenshake and postprocessing, the only thing is that you might consider picking a colorpallete to make the colors more consistent an pleasing for the eye. Maybe draw the sprites in the same style, I noticed that some of the art is in pixelart and some not. Make an option where you can toggle the postprocessing and the screenshake separetely, I looked in the inspector console and it told me that there is some bug with something to do with the postprocesing in the game, not in the main menu (something to do with my graphics card drivers or with Linux).

Good game overall! Add a credit for me in-game lol. /Mhiw

181. I would add some different shapes and colors to hit. the upgrade system keeps you wanting to play. Sound effects are great. This is meant to be a high score game we want to compete with each other on a leaderboard. perhaps a color shift in the background every 10 levels or so.

I wouldn't say this game is too replayable, however this is certainly a neat little game to play when bored and looking for something to play to pass the time. I enjoyed this game a good bit, and I can see that despite the simplicity of the game, it still manages to entertain. Unfortunately, the game doesn't last very long before you buy everything and upgrade everything available.

After 240 the blocks stopped spawning, but it was fun while it lasted
edit; played again, became invincible at 1500 ish

Not too bad! I think the concept is quite unique and the simple look of the in-game sprites works well with a simple arcade game like this. I think the shop menu would do better with a clearer indicator of how many coins you have (maybe accompany the number in the corner with a dollar symbol or a coin?), some way to tell whether you have enough coins to buy something, and a setting to change the controls for your abilities.

Small graphics critique as well - I'd recommend you redo the text and shop menu, to make it look a bit more polished and coordinated with the rest.

Also, the music seems to be quieter in-game than in the main menu?

After fixing all this, it could definitely become front page material! I'd love to see where this goes from here!
