the game actually looks super similar to mine, but still different
i must be critical, so id say, for a 7 day jam i think it couldve been better. there was lot of issues:
1. when i load the game, it most of the time doesnt even let me start the game, i tried refreshing and i think i noticed it only starts if i click 'play' quick enough.
2. the 1000 score thing got me stayed on the game, but nothing even happened. i thought it WAS a challenge that would reveal something. nope.
3. some random shape appears specifically after i kill 3 cubes i think, and stays forever.
4. even when i lose, the restart button doesnt work if i click, i have to actually press R.
5. game is TOO easy to play... it doesnt get harder.
overall, only good thing about it was that it at least has score system, so its close to the theme, but no thrill to actually wanna 'chase' the highscore, because its not even getting harder.
sorry if this sounds rude or mean, i wish you to improve and i know you will, good luck.
check out my game too :D (but dont review bomb it please T_T)
