ok, now i tested this game some more, and it looks like its a game like Bejeweled. When i made those screenshots, i had color buffers enabled, but it works even without them, so when you go into main menu, you get 60fps, and you get 10fps ingame, maybe even more, i have a pretty shitty pc, so it will probably run better on a better rig.
With latest improvements to fragment program, now main menu displays textures and buttons properly, including that you now can see blocks' colors in-game. The game is much more playable now. Not worthy of "Playable" category, yet, due to still existing horrible graphical glitches. Also logos during startup now display (they're glitchy).
Now when you make a pair, explosions don't leave black traces behind anymore. Also there seems to be somekind of a timer now in-game. The "Next" block shown is no longer glitched out as much and some textures look a little crisper or have less black traces/z-fighting.
